0dccc8ba21 include/debug.h: Move to include/nuttx/debug.h
debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.

A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

239130c1fd mm/mm_heap: add nokasan flag in mm_heap_config_s structure
Support enable/disable the kasan when initialize the heap.
This requirement is from rptun, because rptun use share memory init
the heap and share memory is precious, so we need disable the kasan
feature for rptun's heap to save the share memory.

c158ed2c32 mm/heap: memory alignment before executing kasan_register

c82f44c4f3 mm/mm_heap: add mempool to optimize small block performance
There are many small memory block in NuttX system, eg: struct tcb_s,
struct inode, etc, and several disadvantages about them:
1.Their frequent allocate and free cause the system memory fragmentation.
2.Since each memory block has an overhead, the utilization of small memory
blocks is relatively low, which will cause memory waste.

So we can use mempool to alloc smallo block, to improve alloc speed
and utilization, to reduce fragmentation.
