This tries to be a bit smarter for the OLD behaviour of CMP0116, to glob more relevant directories looking for possible dependencies. The changes are: - Remove some duplication of lines in the `tablegen` function. - Put CURRENT_SOURCE_DIR into `tblgen_includes` (at the front) - Glob all directories in `tblgen_includes` - Give up on `local_tds` which was wrong when using tablegen to compile a file in a different directory (as TargetParser does) - Use `EXTRA_INCLUDES` in TargetParser `tablegen` calls. This is still an under-approximation of what might be included, at least comparing the RISCVTargetParserDef.inc.d (after building `target_parser_gen`), and the list of deps in the ninja file when explicitly setting CMP0116 to OLD. Fixes llvm#144639
