Feature/glslang spirv version (#1256)

* WIP add support for __spirv_version .

* Added IRRequireSPIRVVersionDecoration

* SPIR-V version passed to glslang.
Enable VK wave tests.
Split ExtensionTracker out, so can be cast and used externally to emit.
Added SourceResult.

* Fix warning on Clang.

* Missing hlsl.meta.h

* Refactor communication/parsing of __spirv_version with glslang.

* Fix some debug typos.
Be more precise in handling of substring handling.

* Make glslang forwards and backwards binary compatible.

* Small comment improvements.

* Added slang-spirv-target-info.h/cpp

* Fix for major/minor on gcc.

* Another fix for gcc/clang.

* VS projects include slang-spirv-target-info.h/cpp

* Removed SPIRVTargetInfo
Added SemanticVersion.
Don't bother with passing a target to glslang. Should be separate from 'version'.

* Renamed slang-emit-glsl-extension-tracker.cpp/.h -> slang-glsl-extension-tracker.cpp/.h
Fixed some VS project issues.

* Fix a comment.

* Added slang-semantic-version.cpp/.h

* Added slang-glsl-extension-tracker.cpp/.h

* Added split that can check for input has all been parsed.

* Fix problem on x86 win build.
