Richard Elberger a84f51003a armv9: reconcile critical section, add stack overflow MTE fix, per-task VL
- Restore portENABLE_INTERRUPTS() in uxPortSetInterruptMask to match
  upstream ARM_AARCH64_SRE port behavior (PMR masking is sufficient).

- Fix stack_macros.h method 2 overflow check: strip MTE address tags
  from pxStack before dereferencing watermark bytes (prevents tag
  mismatch fault) and before pointer comparison (prevents false trigger).

- Add configARMV9_TASK_VL support: save/restore ZCR_EL1 per-task,
  vPortTaskSetVL() API, initial frame includes ZCR=0xF (max VL).
  Validated on FVP at sve.veclen=4; veclen=2 has a known RDVL
  coherency issue under investigation with Arm.

Each real time kernel port consists of three files that contain the core kernel
components and are common to every port, and one or more files that are
specific to a particular microcontroller and/or compiler.


+ The FreeRTOS/Source/Portable/MemMang directory contains the five sample
memory allocators as described on the https://www.FreeRTOS.org WEB site.

+ The other directories each contain files specific to a particular
microcontroller or compiler, where the directory name denotes the compiler
specific files the directory contains.



For example, if you are interested in the [compiler] port for the [architecture]
microcontroller, then the port specific files are contained in
FreeRTOS/Source/Portable/[compiler]/[architecture] directory.  If this is the
only port you are interested in then all the other directories can be
ignored.
