Support for PDB output from DXC (#2693)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Add versioning to CompileOptions for DownstreamCompiler so we can add new options without breaking binary interface.

* Add support for debug info format to API/command line processing.

* Small simplification.

* Add support for adding PDB output from a compilation.

* Use builtin offset of directly.

* Fix typo in debug.
