[clangd] Avoid scanning up to end of file on each comment!
Assigning char* (pointing at comment start) to StringRef was causing us
to scan the rest of the source file looking for the null terminator.
This seems to be eating about 8% of our *total* CPU!
While fixing this, factor out the common bits from the two places we're
parsing IWYU pragmas.
