Subject: Emit errors when invalid capabilities are used (#4510)

* Fix invalid capabilities being allowed

fixes: #4506
fixes: #4508

1. As per #4506, no longer allow invalid `[require(...)]`
2. As per #4508, no longer allow mismatch between `case` and `require` of a calling function
3. Fixes incorrect hlsl.meta capabilities
4. Added a ref to the parent function/decl for when erroring with capabilities to help debug meta.slang files for when weird source locations are generated.

* rename vars and copy lambdas by value

* fix some more capabilities

* incorrect capabilities on a texture test

* push capabilities fix

note: seperated capabilities for glsl,spirv,cuda,hlsl since not all functions support all targets (source of capability error)

* fix cmd line arg by using `xslang` to passthrough to slangc

* let auto-infer run for certain capabilities to reduce simple mistakes
