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.

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.
