[lldb] Add MacroQualified switch cases for r360109

Summary:
r360109 added a new enum case, causing lldb build to fail with several errors like:
lldb/source/Symbol/ClangASTContext.cpp:4342:11: error: enumeration value 'MacroQualified' not handled in switch [-Werror,-Wswitch]
  switch (qual_type->getTypeClass()) {
          ^
This adds the missing switch cases.
I'm not an lldb maintainer and just used my best judgement that it's probably expected that we break in these cases. Feel free to ping / revert / fix this change if this behavior is not appropriate.
