Subject: Split out target code generation from CLikeSourceEmitter (#976)

* * 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.

* * CLikeSourceEmitter::CInfo -> Desc
* Functions to get and find CodeGenTarget by name
* Split out empty language impls
* Create an impl based on SourceStyle

* * CodeGenTarget conversion to and from string

* Move HLSL specific functions to HLSLEmitSource.

* Emitting texture and image types.

* Move move GLSL specific functionality to GLSLSourceEmitter

* Split more out of slang-emit-c-like

* Refactor more out of slang-emit-c-like

* * tryEmitIRInstExprImpl(IRInst* inst, IREmitMode mode, const EmitOpInfo& inOuterPrec)
* Fix bug around output of uintBitsToFloat

* More work refactoring out target specifics from slang-emit-c-like

* Move functions that are only implemented once in GLSL impl into their Impl method.

* Move rate qualification out of slang-emit-c-like

* * Added getEmitOpForOp - allows for table usage so different ops can be dealt with the same way
* Moved vector comparison to slang-emit-glsl
*

* * Use EmitOpInfo to control output in slang-emit-c-like.cpp for unary ops

* Move more functionality from CLikeSourceEmitter to HLSLSourceEmitter

* Make output of parameters implementaion specific.

* Extracted interpolation modifiers.

* Remove IR from methods that don't need them.

* Remove IR from method names.

* Refactor handling of output of types - to make the impls implement the full path without lots of cases for specific impls

* Add variable declaration modifiers and matrix layout to larget specific in slang-emit.

* Make target specific internal functions _ prefixed.
