[llvm-rc] Serialize STRINGTABLE statements to .res file.

This allows llvm-rc to serialize STRINGTABLE resources.

These are output in an unusual way: we locate them at the end of the
file, and strings are merged into bundles of max 16 strings, depending
on their IDs, language, and characteristics.
