The inclusion of `fsl_common.h` solely for defining `NXP_MPU_BASE`
is redundant, as this symbol is not used. Consequently, this
unnecessary inclusion leads to the pervasive inclusion of HAL
headers through kernel headers.
The needed HAL definitions are already included into the NXP MPU
driver implementation via the SoC header.

A common pattern is used throughout llext.c:
ext->mem[ldr->sect_map[sym.st_shndx]]
where ldr->sect_map[sym.st_shndx] actually contains indices from
enum llext_section but ext->mem[] is indexed, using enum llext_mem
values. Fix this by changing ldr->sect_map[] to actually contain
enum llext_mem values.

After some further investigation, I could find the current solution to
enable zbus channels (by using ZBUS_CHAN_DECLARE) to be used in C++
files, which generates a warning when we mix C and C++ code. This fixes
the issue by using an approach to add the extern keyword only when the
file is being compiled with a C++ compiler.

The icmsg and icmsg_me backends has limitations in context of
concurrent access to single instance. Some limitations are:
* sending by more thread at the same time may cause -EBUSY
* allocating TX buffer will cause errors in other threads that want
to allocate before first thread sent the message,
* during no-copy receive, when RX buffer is on hold receiving is
totally blocked.
This backend resolves those limitations by adding dynamically allocated
buffers on shared memory next to ICmsg circular buffer. The data is
passed using those buffers, so concurrency is not a problem. The ICmsg
is used only to pass short 2-byte messages containing references to
those buffers. The backend also supports multiple endpoint.
The ipc/icmsg_me sample was modified to support this backend.
