Implement Cache Management Operations (CMO) defined by
RISC-V spec https://github.com/riscv/riscv-CMOs.
Notes:
1. CMO only supports block based Operations. Meaning cache
flush/invd/clean Operations are not available for the entire
range. In that case we fallback on fence.i instructions.
2. Operations are implemented using Opcodes to make them compiler
independent. binutils 2.39+ compilers support CMO instructions.
Test:
1. Ensured correct instructions are refelecting in asm
2. Qemu implements basic support for CMO operations in that it allwos
instructions without exceptions. Verified it works properly in
that sense.
3. SG2042Pkg implements CMO-like instructions. It was verified that
CpuFlushCpuDataCache works fine. This more of less
confirms that framework is alright.
4. TODO: Once Silicon is available with exact instructions, we will
further verify this.

There are different ways to manage cache on RISC-V Processors.
One way is to use fence instruction. Another way is to use CPU
specific cache management operation instructions ratified as
per RISC-V ISA specifications to be introduced in future
patches. Current method is fence instruction based, rename the
function accordingly to add that clarity.

The current CalculateCrc16Ansi implementation does the following:
1) Invert the passed checksum
2) Calculate the new checksum by going through data and using the
lookup table
3) Invert it back again
This emulated my design for CalculateCrc32c, where 0 is
passed as the initial checksum, and it inverts in the end.
However, CRC16 does not invert the checksum on input and output.
So this is incorrect.
Fix the problem by not inverting input checksums nor output checksums.
Callers should now pass CRC16ANSI_INIT as the initial value instead of
"0". This is a breaking change.
This problem was found out-of-list when older ext4 filesystems
(that use crc16 checksums) failed to mount with "corruption".

Currently, TDVF has not handled the retry results and always clears
