Add wave intrinsics

[RayMarch]

Wgsl has subgroup operations now
https://www.w3.org/TR/WGSL/#subgroup-ops
we should add them to the shame api

Steps

• define expr enum SubgroupOperations containing all the functions
• impl TypeCheck for SubgroupOperations
• add shame::any::Any associated functions for every subgroup op
• add typed rust frontend for those Any functions.
• add documentation to the public rust frontend functions

The Any api is designed to match the WGSL spec, so it uses their subgroup terminology, however the rust frontend does not use this terminology for reasons outlined here:
