  [Clang] Fix how ReadMacroParameterList handles comments in macro parameter-list when in -CC mode

Currently when in -CC mode when processing a function like macro
ReadMacroParameterList(...) does not handle the case where there is a comment
embedded in the parameter-list.

Instead of using LexUnexpandedToken(...) I switched to using
LexUnexpandedNonComment(...) which eats comments while lexing.
