This particular test was ignored in CI because, when using
platform_key, Twister picks the specific platform very early in
the process and it is possible that the chosen one is later
filtered out. To fix this, use the `integration_platforms` key
instead to specify the platforms where the test is expected to
complete successfully.

The latest commits allow llexts to be built on any architecture, even on
those where llext loading is still unsupported, which is very useful for
testing purposes. This means that the LOADER_BUILD_ONLY logic that was
added for this purpose in 1408d1e5b8 is no longer needed.

LLEXT on Xtensa now supports both shared and relocatable (partially
linked) extensions. This commit adds a copy of the LLEXT test for the
relocatable case.

This patch adds support for custom commands to be executed during the
build of an llext target. The commands can be executed at different
points in the build process:
- PRE_BUILD: Before the llext code is linked.
- POST_BUILD: After the llext code is built, but before packaging
it in an .llext file.
- POST_PKG: After the llext file has been created.
Note that PRE_BUILD is not supported for ARM targets, as in that case
object files are used directly and there is no actual linking step.
The commands can be added using the new add_llext_command() function.
An example usage of it, along with some target properties, is added to
the hello_world test case.

Check if syscalls can be accessed from both kernel and userspace, and if
optimised away ones indeed point to NULL.

Fix conflict between commit ce24394437 ("llext: add object test case")
and commit 1408d1e5b8 ("tests: llext: compile architectures not
supported yet") which were tested separately but merged at the same
time.
Github "Merge Queues" can avoid this (and save resources) but:
- they're not used by Zephyr CI
- they provide confusing feedback

For now llext supports a very limited number of architectures. This
restriction is enforced by add_llext_target() in CMake at configuration
time.
Add a new `LOADER_BUILD_ONLY` conditional in tests/subsys/llext/simple/
and a new `llext.simple.loader_build`, `build_only` test that does not
invoke `add_llext_target()` and only compiles the llext framework code.
This helps find and fix bugs in `subsys/llext/*.c` and make it ready to
be used when add_llext_target() limitations are lifted.
Note this is pure `tests/` change without any change in the actual llext
framework code. The existing test is only modified to conditionally
invoke add_llext_target().

Validate the new relocations for BL and BLX instructions by
creating a new test extension which contains a chain of global
functions in a pseudo random order to (hopefully) generate
relative jumps in both positive and negative directions.

The simple test is there to test the API and simple extensions in
unison. Hello world was intended to be the first not the only extension
being tested.
Also refactors the entry thread to allow for usermode potentially by
passing the pointer to the function symbol rather than having it look it
up directly.
