tint: Add type constructors and converters support to intrinsic-gen

Browse Source 
These are currently not used, but the first step towards moving type
constructors and converters over to using the intrinisc table.

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