Sampler Feedback improvements (#1475)
* Add the Feedback texture types.
Depreciate SLANG_RESOURCE_EXT_SHAPE_MASK.
* Starting point to test sampler feedback.
* WIP on FeedbackSampler.
* Use __target_intrinsic to override the output of sampler feedback types.
* Use newer generic syntax for FeedbackTexture.
* Reflects Feedback type.
* SLANG_TYPE_KIND_TEXTURE_FEEDBACK -> SLANG_TYPE_KIND_FEEDBACK
* Added reflection test.
* Reneable issue with generics in sampler-feedback-basic.slang
* Add methods to FeedbackTexture2D/Array.
Make test cover test cases.
* Sampler feedback produces DXC code.
* Disabled Sampler feedback test - as requires newer version of DXC.
* Fix bug in reflection tool output.
* Fix problem with direct-spirv-emit.slang.expected due to update to glslang.
* Fix direct-spirv-emit.slang
* Use SLANG_RESOURCE_EXT_SHAPE_MASK again
* Make Feedback be emitted as a textue type prefix.
* Add support for GetDimensions to FeedbackTexture2D
* WIP on CPU sampler feedback.
Update of target compatibility.
* Fix some bugs in C++ feedback sampler.
Fix GetDimensions for FeedbackTextures.
Run 'Compile' test for CPU compute feedback texture test.
Update target-compatability.md
* Fix GetDimensions call on feedback sampler.
* Small documentation improvements.
