We have removed the use of pthread_attr_setstack and as a result,
the task stack is no longer used as the corresponding pthread's stack.
There is no use of calling pthread_attr_setstacksize as the default is
always good enough and we don't need to handle OS specific cases.
This PR simplifies the code by removing the call to pthread_attr_setstacksize.

* 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

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.

In environments that do not support static allocation
(configSUPPORT_STATIC_ALLOCATION == 0), at prvCreateIdleTasks(), call
xCreateTask() and compare its return value to pdFAIL to check whether
xCreateTask() failed. However, xCreateTask() returns
errCOULD_NOT_ALLOCATE_REQUIRED_MEMORY as the error value, so the
result of this comparison is always false.
This commit fixes this problem by changing the return value comparison
to pdPASS instead of pdFAIL.

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.

2. Add the missing prototypes for v1.
3. Add the corresponding mapping to mpu_wrappers.h.
4. Update MPU v1 wrappers for vTaskList and vTaskGetRunTimeStats.

Event Groups: snapshot xEventGroupSetBits returning value while in
vTaskSuspendAll. Fixes uxEventBits dereference after event group
deleted by higher priority thread.
When a task deletes itself, it calls portPRE_TASK_DELETE_HOOK which
translates to vPortCloseRunningThread on the Windows port.
vPortCloseRunningThread never returns and as a result,
taskYIELD_WITHIN_API in vTaskDelete does not get called. As a result,
the next task is not scheduled when configUSE_PREEMPTION is set to 0.
This change records that a yield is pending so that the next tick
interrupt switches out the task that was deleted.

The original implementation only initializes the first

might not behave as expected.
When configUSE_PREEMPTION == 1 & configUSE_TIME_SLICING == 1,
replace setting xYieldRequiredForCore[ xCoreID ] with setting
xYieldPendings[ xCoreID ].
And when configUSE_PREEMPTION == 1, simplify the check
condition to only check xYieldPendings[ xCoreID ].

This PR adds support for vApplicationFPUSafeIRQHandler. The application
writer needs to name their IRQ handler as:
1. vApplicationIRQHandler if the IRQ handler does not use FPU registers.
2. vApplicationFPUSafeIRQHandler is the IRQ handler uses FPU registers.
When the application uses vApplicationFPUSafeIRQHandler, a default
implementation of vApplicationIRQHandler is used which stores FPU
registers and then calls vApplicationFPUSafeIRQHandler.
* Reset xNextTaskUnblockTime in task notify FromISR APIs
If a task is blocked waiting for a notification then
xNextTaskUnblockTime might be set to the blocked task's timeout time. If
the task is unblocked for a reason other than a timeout
xNextTaskUnblockTime is normally left unchanged, because it will
automatically get reset to a new value when the tick count equals
xNextTaskUnblockTime. However if tickless idle is used it is important
to enter sleep mode at the earliest possible time - so reset
xNextTaskUnblockTime here to ensure it is updated at the earliest
possible time.

This PR makes the following improvements to the ARM_CRx_No_GIC port-
1. Remove inline assembly and move all the assembly code to the portASM.S
file.
2. Add support for configUSE_TASK_FPU_SUPPORT -
- When configUSE_TASK_FPU_SUPPORT is defined to 1, tasks are created
without floating point context. Tasks that want to use floating point, need
to call portTASK_USES_FLOATING_POINT(). This is the current behavior.
- When configUSE_TASK_FPU_SUPPORT is defined to 2, each task is created
with a floating point context.
If left undefined, configUSE_TASK_FPU_SUPPORT defaults to 1 for backward compatibility.
3. The application writer can now implement vApplicationSVCHandler to handle the
SVC calls raised within the application. SVC 0 is used for the yield kernel operation
and the application can use all the SVC calls other than 0.

FreeRTOS MPU: Add privileged execute never MPU attribute
A new MPU region attribute Privileged eXecute Never (PXN)
is introduced in Armv8.1-M architecture, where if an MPU
region has PXN attribute set and the processor attempts
to execute the code inside with privileged level,
the Memory Management Fault exception would be triggered,
with IACCVIOL bit in MemManage Fault State Register set
to 1. The PXN feature allows privileged software to ensure
specific application tasks (threads) to execute in
unprivileged level only.

In `prvCheckForRunStateChange()`, enabling interrupts should cause this core to immediately service the pending interrupt and yield. Upon the next scheduling of the task, the assertion `configASSERT(pxThisTCB->xTaskRunState != taskTASK_SCHEDULED_TO_YIELD);` may not be true, as other cores could have requested a yield for this task before it evaluates its run state within the assertion. To address this, the task re-evaluates its run state in critical section within a loop until it is eligible for execution, which is the current implementation. Consequently, this assertion should be removed to ensure correct behavior.
