DXC as DownstreamCompiler (#1845)

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

* WIP Fxc as downstream compiler.

* First pass FXC downstream compiler working.

* GCC compile fix.

* Fix FXC parsing issue.

* Special case filesystem access.

* Use StringUtil getSlice.

* Fix isses with not emitting source for FXC.

* WIP on DXC.

* Small fixes for DXBC handling.

* Removed DXC from ParseDiagnosticUtil (can use generic)
Try to improve output for notes from DXC.
