[SDK] Fix the implementation of the FsRtlIsAnsiCharacter* macros.

Browse source 
These macros should be implemented using the FsRtlTestAnsiCharacter() macro
that performs extended tests, especially for buffer overruns.
This fixes FsRtlIsAnsiCharacterWild(), FsRtlIsAnsiCharacterLegalFat(),
FsRtlIsAnsiCharacterLegalHpfs(), FsRtlIsAnsiCharacterLegalNtfs().
