Implementing code to support Cache Management Operations (CMO) defined by
RISC-V CMO instructions.https://github.com/riscv/riscv-CMOs
This is a re-write of original series v5.
The patchset contains 5 patches- created based on V5 feedback.
1. Restructuring of existing code and move instruction declarations into BaseLib
2. Renaming existing functions to denote type of instruction used to maanage cache.
   This is useful for further patches where more cache management instructions are added.
3. Add the new cache maintenance operations to BaseLib, including the
	 new assembly instruction encodings.
4. Update BaseCacheMaintenanceLib (utilizing the new BaseLib primitives)
5. Add platform level PCD to allow overriding of RISC-V features.
