This change is added to incorporate basic implementation for
CRC16-CCITT-FALSE algorithm.
This function is useful for providing CRC16 value used in other data
structures that requires CRC16 value that complies with JEDEC SPD
requirements, i.e. BDAT table.
The lookup table is inherited from `https://crccalc.com/` and the result
values are also compared against this site.

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".

CalculateCrc32() bases on the initialized mCrcTable. When CalculateCrc32()
is used, mCrcTable will take 1KB size in the image. When CalculateCrc32()
is not used, mCrcTable will not be built in the image, and no size impact.
