ci: Use organisation-level AWS secrets

This commit updates the CI workflows to use the `zephyrproject-rtos`
organisation-level AWS secrets instead of the repository-level secrets.

Using organisation-level secrets allows more centralised management of
the access keys used throughout the GitHub Actions CI infrastructure.

Note that the `AWS_*_ACCESS_KEY_ID` is now stored in plaintext as a
variable instead of a secret because it is equivalent to username and
needs to be identifiable for management and audit purposes.

(cherry picked from commit 8233f8ef91)

-**Notes (delete this)**
-Github Discussions (https://github.com/zephyrproject-rtos/zephyr/discussions)
-are available to first verify that the issue is a genuine Zephyr bug and not a
-consequence of Zephyr services misuse.
-
-This issue list is only for bugs in the main Zephyr code base
-(https://github.com/zephyrproject-rtos/zephyr/). If the bug is for a project
-fork (such as NCS) specific feature, please open an issue in the fork project
-instead.
-
-**Describe the bug**
-A clear and concise description of what the bug is.
-
-Please also mention any information which could help others to understand
-the problem you're facing:
- - What target platform are you using?
- - What have you tried to diagnose or workaround this issue?
- - Is this a regression? If yes, have you been able to "git bisect" it to a
-   specific commit?
- - ...
-
-**To Reproduce**
-Steps to reproduce the behavior:
-1. mkdir build; cd build
-2. cmake -DBOARD=board\_xyz
-3. make
-4. See error
-
-**Expected behavior**
-A clear and concise description of what you expected to happen.
-
-**Impact**
-What impact does this issue have on your progress (e.g., annoyance, showstopper)
-
-**Logs and console output**
-If applicable, add console logs or other types of debug information
-e.g Wireshark capture or Logic analyzer capture (upload in zip archive).
-copy-and-paste text and put a code fence (\`\`\`) before and after, to help
-explain the issue. (if unable to obtain text log, add a screenshot)
-
-**Environment (please complete the following information):**
- - OS: (e.g. Linux, MacOS, Windows)
- - Toolchain (e.g Zephyr SDK, ...)
- - Commit SHA or Version used
-
-**Additional context**
-Add any other context that could be relevant to your issue, such as pin setting,

+	help
+	  This option signifies that the target uses MCUboot as a bootloader,
+	  or in other words that the image is to be chain-loaded by MCUboot.
+	  This sets several required build system and Device Tree options in
+	  order for the image generated to be bootable using the MCUboot open
+	  source bootloader. Currently this includes:
+
+	    * Setting ROM_START_OFFSET to a default value that allows space
+	      for the MCUboot image header
+	    * Activating SW_VECTOR_RELAY_CLIENT on Cortex-M0
+	      (or Armv8-M baseline) targets with no built-in vector relocation
+	      mechanisms
+
+	  By default, this option instructs Zephyr to initialize the core
+	  architecture HW registers during boot, when this is supported by
+	  the application. This removes the need by MCUboot to reset
+	  the core registers' state itself.

+
+	  If set to a non-empty value, the build system tries to

+	  The signed binaries are placed in the build directory
+	  at zephyr/zephyr.signed.bin and zephyr/zephyr.signed.hex.
+
+	  The file names can be customized with CONFIG_KERNEL_BIN_NAME.
+	  The existence of bin and hex files depends on CONFIG_BUILD_OUTPUT_BIN
+	  and CONFIG_BUILD_OUTPUT_HEX.
+
+	  This option should contain a path to the same file as the
+	  BOOT_SIGNATURE_KEY_FILE option in your MCUboot .config. The path
+	  may be absolute or relative to the west workspace topdir. (The MCUboot
+	  config option is used for the MCUboot bootloader image; this option is
+	  for your application which is to be loaded by MCUboot. The MCUboot
+	  config option can be a relative path from the MCUboot repository
+	  root.)

+	help
+	  The file contains the public key that is used to encrypt the
+	  ephemeral key that encrypts the image. The corresponding
+	  private key is hard coded in the MCUboot source code and is
+	  used to decrypt the ephemeral key that is embedded in the
+	  image. The file is in PEM format.
+
+	  If set to a non-empty value, the build system tries to
+	  sign and encrypt the final binaries using a 'west sign -t imgtool'
+	  command. The binaries are placed in the build directory at
+	  zephyr/zephyr.signed.encrypted.bin and
+	  zephyr/zephyr.signed.encrypted.hex.

+	  The file names can be customized with CONFIG_KERNEL_BIN_NAME.
+	  The existence of bin and hex files depends on CONFIG_BUILD_OUTPUT_BIN
+	  and CONFIG_BUILD_OUTPUT_HEX.
+

+
+	  If left empty, you must encrypt the Zephyr binaries manually.
+
+config MCUBOOT_EXTRA_IMGTOOL_ARGS

+	  If CONFIG_MCUBOOT_SIGNATURE_KEY_FILE is a non-empty string,

+	  For example, you could set this to "--version 1.2".
+
+config MCUBOOT_GENERATE_UNSIGNED_IMAGE

-
-	  Thumb-2 technology is the instruction set underlying the ARM Cortex
-	  architecture which provides enhanced levels of performance, energy
-	  efficiency, and code density for a wide range of embedded
-	  applications.
-
-	  Thumb-2 technology builds on the success of Thumb, the innovative
-	  high code density instruction set for ARM microprocessor cores, to
-	  increase the power of the ARM microprocessor core available to
-	  developers of low cost, high performance systems.
-
-	  The technology is backwards compatible with existing ARM and Thumb
-	  solutions, while significantly extending the features available to
-	  the Thumb instructions set. This allows more of the application to
-	  benefit from the best in class code density of Thumb.
-
-	  For performance optimized code Thumb-2 technology uses 31 percent
-	  less memory to reduce system cost, while providing up to 38 percent
-	  higher performance than existing high density code, which can be used
-	  to prolong battery-life or to enrich the product feature set. Thumb-2
-	  technology is featured in the  processor, and in all ARMv7
-	  architecture-based processors.
-
-config ISA_ARM
-	bool
-	help
-	  From: https://developer.arm.com/products/architecture/instruction-sets/a32-and-t32-instruction-sets
-
-	  A32 instructions, known as Arm instructions in pre-Armv8 architectures,
-	  are 32 bits wide, and are aligned on 4-byte boundaries. A32 instructions
-	  are supported by both A-profile and R-profile architectures.
-
-	  A32 was traditionally used in applications requiring the highest
-	  performance, or for handling hardware exceptions such as interrupts and
-	  processor start-up. Much of its functionality was subsumed into T32 with
-	  the introduction of Thumb-2 technology.
-
-config ASSEMBLER_ISA_THUMB2
-	bool
-	default y if ISA_THUMB2 && !ISA_ARM

-	help
-	  This helper symbol specifies the default target instruction set for
-	  the assembler.
-
-	  When only the Thumb-2 ISA is supported (i.e. on Cortex-M cores), the
-	  assembler must use the Thumb-2 instruction set.
-
-	  When both the Thumb-2 and ARM ISAs are supported (i.e. on Cortex-A
-	  and Cortex-R cores), the assembler must use the ARM instruction set
-	  because the architecture assembly code makes use of the ARM
-	  instructions.
-
-config COMPILER_ISA_THUMB2

-	       C++ languages; in fact, this symbol refers to all forms of
-	       "compiled" code.
-
-	       When an additional natively-compiled language support is added

-	bool "Align stacks on double-words (8 octets)"
-	default y
-	help
-	  This is needed to conform to AAPCS, the procedure call standard for
-	  the ARM. It wastes stack space. The option also enforces alignment
-	  of stack upon exception entry on Cortex-M3 and Cortex-M4 (ARMv7-M).
-	  Note that for ARMv6-M, ARMv8-M, and Cortex-M7 MCUs stack alignment
-	  on exception entry is enabled by default and it is not configurable.
-
-config RUNTIME_NMI

-	help
-	  This option selects the ARM alternative format for FP16.  This
