Ederson de Souza 321e395a8f linker: Include libkernel.a in the whole-archive when llext is enabled 
Differently from other libraries, which are included whole in the final
Zephyr ELF, libkernel.a itself isn't. Assuming this is intended to
enable optimisations (if it isn't, this patch will break things) - linker
can remove parts of the kernel that are not used by the application.

However, when considering Linkable Loadable Extensions (llext), this
optimisations can be counterproductive: for instance, syscalls that are
not used by the application won't be available for extensions. It won't
matter if someone "EXPORT_SYMBOL" for them, or even try to keep them
using LINKER_KEEP, they'll be gone.

To avoid that, this patches includes, when CONFIG_LLEXT=y, libkernel.a
inside the linker "whole-archive" block. This ends up making it consider
libkernel.a as a library whose all symbols should be kept. Note this
doesn't mean that all symbols will be there - things compiled out via
Kconfig will naturally still be out.
