Add warnings for file header pragmas that appear in the body of a module (#20385)wip/parse-errs
Once we are done parsing the header of a module to obtain the options, we
look through the rest of the tokens in order to determine if they contain any
misplaced file header pragmas that would usually be ignored, potentially
resulting in bad error messages.
The warnings are reported immediately so that later errors don't shadow
over potentially helpful warnings.
