AppPkg: Replace all occurrences of ` within comments with '.

AppPkg: Replace all occurrences of ` within comments with '.

Within the Ia32 and X64 pyconfig.h files, there are 178 occurrences
of an accent character, `, being used instead of a regular single quote, ',
within comments.

Example:
    OLD:  `foobar'
    NEW: 'foobar'

The same changes are applied to both
AppPkg/Applications/Python/Ia32/pyconfig.h and
AppPkg/Applications/Python/X64/pyconfig.h.
