cmake: mcuboot: Flash encrypted image when loading to RAM

Browse Source 
When both `SB_CONFIG_MCUBOOT_MODE_RAM_LOAD` and `SB_CONFIG_BOOT_ENCRYPTION`
are enabled, MCUBoot loads an encrypted image from flash, decrypts it,
and then executes it from RAM.

Previously, the unencrypted image was being flashed. This caused a boot
failure because MCUBoot would attempt to decrypt an unencrypted image.

This commit ensures the encrypted image is flashed when this
configuration is active, allowing the system to boot correctly.
