tint: Add operator support to intrinsic-gen

Browse Source 
Adapt the builtin parsing and resolving to also support operators.
Will be used to generate intrinsic table entries for operators.

This will simplify maintenance of the operators, and will greatly
simplify the [AbstractInt -> i32|u32] [AbstractFloat -> f32|f16] logic.
