* armv8-m: Do not overwrite Control register value
The current ARMv8-M FreeRTOS-Kernel Port code
implementation is modified in a way that allows
the CONTROL register's value to be retained
rather than being overwritten.
This is needed for adding PACBTI support as
the special-purpose CONTROL register `PAC_EN`,
`UPAC_EN`, `BTI_EN`, and `UBTI_EN` PACBTI
enablement bits should be configured before calling
`vRestoreContextOfFirstTask()` function which currently
overwrite the value inside the CONTROL register.

* armv8.1-m: Add PACBTI support to kernel non-secure implementation
In this commit, Pointer Authentication, and Branch Target
Identification Extension (PACBTI) support is added for
Non-Secure and Non-TrustZone variants of Cortex-M85
FreeRTOS-Kernel Port.
The PACBTI support is added for Arm Compiler For
Embedded, and IAR toolchains only. The support in
the kernel is not yet enabled for GNU toolchain
due to known issues.

refactor: change methods ENTER|EXIT critical
The read and write of BaseType_t are atomic for a number of ports
and therefore, do not require taskENTER_CRITICAL/taskEXIT_CRITICAL.
This PR introduces portBASE_TYPE_ENTER_CRITICAL and
portBASE_TYPE_EXIT_CRITICAL which default to taskENTER_CRITICAL
and taskEXIT_CRITICAL. The APIs that read/write BaseType_t are updated
to use these new macros.
The next change would to be to define portBASE_TYPE_ENTER_CRITICAL and
portBASE_TYPE_EXIT_CRITICAL to nothing for ports where BaseType_t
read and write are atomic.
