LLEXT-related sections should only be added to the linker script when the
associated CONFIG_LLEXT is enabled. This has been done by checking for this
Kconfig symbol in every linker file, but this creates a lot of boilerplate
for no good reason.
Use the much simpler solution: move the check inside the common linker file
and remove existing "#ifdef CONFIG_LLEXT" checks in all linker files.
