arm-cortex-r82: Add MPU support

Browse source

This commit introduces support for the Memory Protection Unit (MPU)
to the ARM Cortex-R82 port. The MPU enhances system security
by allowing the definition of memory regions with specific access
permissions. The following changes have been made:
- Added MPU configuration functions in `port.c` to set up memory
  regions and their attributes.
- Updated `portASM.S` to include assembly routines for MPU
  and context switching with MPU support.
- Created `mpu_wrappers_v2_asm.c` to provide assembly wrappers for
  MPU operations.
- Updated `portmacro.h` to include MPU-related macros and definitions.
- Modified `task.h` to include MPU-related task attributes.
- Updated `CMakeLists.txt` to include the new MPU source file.
- Enhanced the `README.md` with instructions on MPU configuration.
