Subject: WIP: Support for other source target language (#971)

* WIP: Setting up C/Cpp source compilation targets.

* WIP: Emitting C/CPP.

* WIP: Split out SourceSink, and use it for source output on emit.

* SourceSink -> SourceStream

* * Made SourceStream use m_ prefixing of members.
* Make all methods use lower camel
* Removed methods from SourceStream interface that are not used externally (use _ prefixing)
* Improvements to documentation

* EmitContext is now effectively empty, so just use SharedEmitContext as EmitContext.

* SharedEmitContext -> EmitContext

* Methods to LowerCamel in emit.cpp

* Split out EmitContext and ExtensionUsageTracker into separate files.

* Split out EmitVisitor into slang-c-like-source-emitter files.

* EmitVisitor -> CLikeSourceEmitter

* Tidy up around CLikeSourceEmitter - simplify header.

* Small tidy up - removing repeated comments that are in header.

* Remove EmitContext paramter threading.

* Small tidy up.
Use prefixed macros for slang-c-like-source-emitter.h

* Small tidy up in slang-c-like-source-emitter.cpp

* First pass at splitting out UnmangleContext.

* MangledNameParser -> MangledLexer.

* WIP making EmitOp (EOp) enum available outside of cpp

* Generating EmitOpInfo from macro.

* Split out emit precedence handling.
Don't use kOp_ style anymore, just use an array indexed by EmitOp.

* Disable C simple test for now.

* Keep g++/clang happy with token pasting.

* Fix win32 narrowing warning.
