fcd392f6ce kernel: subsys: lib: drivers: Use k_heap instead of z_mem_pool wrappers
Use the core k_heap API pervasively within our tree instead of the
z_mem_pool wrapper that provided compatibility with the older mempool
implementation.

Almost all of this is straightforward swapping of one alloc/free call
for another.  In a few cases where code was holding onto an old-style
"mem_block" a local compatibility struct with a single field has been
swapped in to keep the invasiveness of the changes down.

Note that not all the relevant changes in this patch have in-tree test
coverage, though I validated that it all builds.

6bc6a67b0e lib/gui/lvgl: Use a sys_heap and not a sys_mem_pool
The sys_mem_pool allocator is a legacy thing.  Use the standard heap
to reduce code size.

6965cf526d kernel: Deprecate k_mem_pool APIs
Mark all k_mem_pool APIs deprecated for future code.  Remaining
internal usage now uses equivalent "z_mem_pool" symbols instead.

Fixes #24358

08ee8b09ba cleanup: include/: move misc/mempool.h to sys/mempool.h
move misc/mempool.h to sys/mempool.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
