Glslang refactor bugfix (#1863)

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

* Fix issue with with SLANG_ENABLE_GLSLANG_SUPPORT

* Update expected output from glslang-error.glsl

* Fix bug in glsl dissassembly.

* Make ExtensionTracker available even if source is not emitted.

* Only explicitly set extension tracker based on capability bits, if we are in pass through.

* Small simplification of invoke sourceEmit.
