Subject: First pass support for Sampler Feedback (#1470)

* 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.
