[clang] Reject ranges getExpansionRangeInFile cannot represent

getExpansionRangeInFile was extracted verbatim and inherited two shortcomings
of the original loop, fixed here before the analyzer's SARIF and HTML consumers
depend on it:

- It mapped the end with getExpansionRange(SourceLocation), which always
  reports a token range, so a char-range input was widened by a whole token.
  Now using the getExpansionRange(CharSourceRange) overload, which keeps the flag.
- It passed reversed ranges through. Consumers walk begin->end; now returning
  nullopt for those, as Lexer::makeFileCharRange already does.

Separate from the extraction so that stays NFC, and out of the consumer fixes
because it changes the shared helper's contract rather than one output.

Both contract changes, plus the invalid- and cross-file-range guards, are
covered by a GetExpansionRangeInFile unit test in
clang/unittests/Frontend/TextDiagnosticTest.cpp.
