Armv8.1-m: Add pacbti support (#1147)
* copyright-checker: Add FreeRTOS Arm collab copyright

FreeRTOS Arm collab files shall have both Amazon's
and Arm's copyright headers. Hence, the copyright
checker is modified to check for both copyrights.

* armv8-m: Add support for IAR with TFM FREERTOS PORT

As the case for ARMClang, and GCC toolchains, IAR
with TFM FreeRTOS Port support is added.

* 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.

FreeRTOS MPU: Add Privileged eXecute Never MPU attribute support (#1092)
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.

Armv8-M (except Cortex-M23) interrupt priority checking (#673)
* Armv8-M: Formatting changes

Signed-off-by: Devaraj Ranganna <devaraj.ranganna@arm.com>

* Armv8-M: Add support for interrupt priority check

FreeRTOS provides `FromISR` system calls which can be called directly
from interrupt service routines. It is crucial that the priority of
these ISRs is set to same or lower value (numerically higher) than that
of `configMAX_SYSCALL_INTERRUPT_PRIORITY`. For more information refer
to https://www.FreeRTOS.org/RTOS-Cortex-M3-M4.html.

Add a check to trigger an assert when an ISR with priority higher
(numerically lower) than `configMAX_SYSCALL_INTERRUPT_PRIORITY` calls
`FromISR` system calls if `configASSERT` macro is defined.

In addition, add a config option
`configQEMU_DISABLE_INTERRUPT_PRIO_BITS_CHECK` to disable interrupt
priority check while running on QEMU. Based on the discussion
https://gitlab.com/qemu-project/qemu/-/issues/1122, The interrupt
priority bits in QEMU do not match the real hardware. Therefore the
assert that checks the number of implemented bits and __NVIC_PRIO_BITS
will always fail. The config option
 `configQEMU_DISABLE_INTERRUPT_PRIO_BITS_CHECK` should be defined in the
`FreeRTOSConfig.h` for QEMU targets.

* Use SHPR2 for calculating interrupt priority bits

This removes the dependency on the secure software to mark the interrupt
as non-secure.

Add suppport for ARM CM55 (#494)
* Add supposrt for ARM CM55

* Fix file header

* Remove duplicate code

* Refactor portmacro.h

1. portmacro.h is re-factored into 2 parts - portmacrocommon.h which is
   common to all ARMv8-M ports and portmacro.h which is different for
   different compiler and architecture. This enables us to provide
   Cortex-M55 ports without code duplication.
2. Update copy_files.py so that it copies Cortex-M55 ports correctly -
   all files except portmacro.h are used from Cortex-M33 ports.
