Subject: Review improvements on #971: WIP: Support for other source target
 languages (#974)

* * Added SourceStyle to CLikeSourceEmitter, to limit cases to actual target types.
* Made Impl methods _ prefixed
* Small tidyup

* * SourceStream -> SourceWriter
* use slang-emit- prefix on SourceWriter file

* * Remove EmitContext -> merge into CLikeSourceEmitter

* slang-c-like-source-emitter -> slang-emit-source.cpp

* ExtensionUsageTracker -> GLSLExtensionTracker
slang-extension-usage-tracker.cpp/.h -> slang-emit-glsl-extension-tracker.cpp/.h

* emit-source.cpp.h -> emit-c-like.cpp/.h

* Small fix to move where some _ prefixed functions are declared in CLikeSourceEmitter.
