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.

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.
