Update xTaskGetIdleTaskHandle() For SMP (#868)
* Update xTaskGetIdleTaskHandle() in SMP
This commit updates xTaskGetIdleTaskHandle() for SMP in the following ways:
- xTaskGetIdleTaskHandle() no longer accepts xCoreID argument in SMP so that
there is not change in API between single-core and SMP
- xTaskGetIdleTaskHandle() now returns the Active idle task handle in SMP,
which matches the behavior in single-core.
- Added xTaskGetIdleTaskHandleForCore() in SMP which accepts an xCoreID
argument. This function can be used to obtain the Passive idle task handles.

Update system call entry mechanism (#898)
Earlier the System Call entry from an unprivileged task
looked like:
1. SVC for entering system call.
2. System call implementation.
3. SVC for exiting system call.
Now, the system call entry needs to make only one SVC
call and everything else is handled internally.
This PR also makes the following changes:
1. Update the Access Control List (ACL) mechanism to
grant access to all the kernel objects before the
scheduler is started.
2. Add one struct param for system calls with 5 parameters.
This removes the need for special handling for system
calls with 5 parameters.
3. Remove raise privilege SVC when MPU wrapper v2 is used.
4. Add additional run time parameter checks to MPU wrappers
for xTaskGenericNotify and xQueueTakeMutexRecursive APIs.

Kernel Checker CI Workflow File Updates (#804)

This PR fixes the bug described in the following issue:
https://github.com/FreeRTOS/FreeRTOS-Kernel/issues/612.
This was originally contributed in the following PR:
https://github.com/FreeRTOS/FreeRTOS-Kernel/pull/625.
The implementation suspends the scheduler before exiting the
critical section (i.e. before enabling interrupts). If we do not do
so, a notification sent from an ISR, which happens after exiting
the critical section and before suspending the scheduler, will
get lost. The sequence of events will be:
1. Exit critical section.
2. Interrupt - ISR calls xTaskNotifyFromISR which adds the task to
the Ready list.
3. Suspend scheduler.
4. prvAddCurrentTaskToDelayedList moves the task to the delayed
or suspended list.
5. Resume scheduler does not touch the task (because it is not on
the pendingReady list), effectively losing the notification from
the ISR.
The same does not happen when we suspend the scheduler before
exiting the critical section. The sequence of events in this case will
be:
1. Suspend scheduler.
2. Exit critical section.
3. Interrupt - ISR calls xTaskNotifyFromISR which adds the task to
the pendingReady list as the scheduler is suspended.
4. prvAddCurrentTaskToDelayedList adds the task to delayed or
suspended list. Note that this operation does not nullify the add
to pendingReady list done in the above step because a different
list item, namely xEventListItem, is used for adding the task to the
pendingReady list. In other words, the task still remains on the
pendingReady list.
5. Resume scheduler moves the task from pendingReady list to the Ready list.

bugfix: correct computation of stack size on Mac Posix port (#816)
Aligns the stack end to a page boundary before computing its
size, since the size depends on both the start and end.
The original change which introduced stack alignment (#674)
only worked for cases where the round + trunc operation would
wind up within the same area, but would lead to segfaults in
other cases.
Also adds a typecast to the `mach_vm_round_page()` call, as
it is actually a macro which casts to `mach_vm_offset_t` and
the result here is used as a `StackType_t` pointer.
Tested on ARM64 and Intel MacOS, as well as ARM64 and Intel
Linux. The test code included a single-task case, as well
as a case with two tasks passing queue messages.
