[OMM] Add DXR Entry point test, non-library target test, conforming tests to spec. (microsoft#7281)

This PR adds 2 tests that were mentioned in the spec that haven't yet
been added.
1. A test that makes sure that restricted flags are diagnosed in DXR
entry shaders.
2. A test that makes sure that no diagnostics are emitted when a
restricted flag is used for a subobject in a non-library shadaer target.

Fixes microsoft#7282
