portPOINTER_SIZE_TYPE is used in FreeRTOS to store both pointer and integer values. Using a plain integer type for this purpose is unsafe on architectures that distinguish between pointers and integers, where an integer type (e.g. uint64_t) may not be able to represent all pointer values. The standard intptr_t type is explicitly defined to safely hold either a pointer or an integer. This commit changes portPOINTER_SIZE_TYPE to intptr_t, similar to the existing POSIX port, improving portability of the RISC-V port. Similarly, portSTACK_TYPE is used to store word-sized values on the stack that may represent either integers or pointers, and is often cast to pointer types. Changing it to uintptr_t makes this usage explicit and correct, improving portability, intent, and safety for capability-based extensions such as CHERI-RISC-V.

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.
