[tint] Add subgroup_id builtin value Only valid in compute shaders as a u32 input. Currently gated on `chromium_experimental_subgroup_matrix` although we can hopefully move it to `subgroups` if we can reliably implement it in HLSL and then standardize it. Emit this as `simdgroup_index_in_threadgroup` or `SubgroupId` in MSL and SPIR-V respectively.

[tint][fuzz] Migrate proto definitions to common lib directory The fuzzing proto depends on the ir proto, so needs to reference it.

Instead of having these leaf node targets reaching into other leaf node directories, move the generated proto targets up into a common utils location. The encode/decode methods for doing IR <-> PB conversion are left in the ir/ directory, becasue they need to access lots of the IR internals.
