Make correct/consistent include capitalization (#1269)

Several #included files were capitalized incorrectly in the case of
files pertaining to the project, or inconsistently in the case of
Windows headers which are typically only relevant where capitalization
doesn't matter. In spite of that, consistent capitalization can be
useful for cross platform stubbing purposes.

This corrects capitalization of a few Dxil* headers and forces
capitalization of Windows-specific headers to be consistent with
the overwhelming majority of other cases.

No functional change, just cross-platform facilitation
