Subject: GLSL SSBO Support (#3400)

* Squash warnings and fix build with SLANG_EMBED_STDLIB

* Add GLSLShaderStorageBuffer magic wrapper

* Make GLSLSSBO not a uniform type

* Buffers are global variables

* Allow creating ssbo aggregate types

* Allow reading from RWSB using builder

* Nicer debug printing for ssbos

* Lower SSBO to RWSB

* Parse interface blocks into wrapped structs

* Lower Interface Block Decls to structs

* remove comment

* Two simple ssbo tests

* Move ssbo pass earlier

* Correct mutable buffer detection

* Do not replace ssbo usages outside of blocks

* Treat GLSLSSBO as a mutable buffer for type layouts

* regenerate vs projects

* Correctly detect ssbo types

* Diagnose illegal ssbo

* remove unreachable code

* neaten

* ci wobble

* Make GLSLSSBO ast handling more uniform

* Add modifier cases for glsl

* Use empty val info for unhandled interface blocks

necessary for ./tests/glsl/out-binding-redeclaration.slang

* more sophisticated modifier check

* Correct ssbo wrapper name
