  [WGSL] Add overloads for vecN constructors

Reviewed by Myles C. Maxfield.

Add the declarations for all the overloads of vec2, vec3 and vec4 constructors.
This requires introducing a couple new constraints, although constraints aren't
validated yet. There's only one overload per constructor disabled with a fixme,
since they require explicitly specifying the type (e.g. vecN<T>(...)), but we
don't currently support that, but will be implemented next.
