Subject: Implement shader subgroup rotate intrinsics (#6878)

* Initial implementation for SPIRV, GLSL and Metal

* test add bool test

* Fix and improve subgroup rotate tests

* Add proper GLSL extensions and proper Metal type checking

* Clean up tests and add diagnostics test for subgroup type for Metal

* Update wave-intrinsics docs
