The nRF54 and nRF92 chips has data cache, which means
the ICMsg and ICBMsg must be configured to follow required
cache alignment of the shared memory.
The `dcache-alignement` needs to be defined for that.

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.

This migrates the subsys code samples to the new Sphinx code-sample
extension, making it easier to find relevant samples when browsing
API reference.
