Move the bulk of the constant evaulation logic out of transform::FoldConstants and into Resolver and sem::Expression.
transform::FoldConstants now replace TypeConstructor nodes that have a constant value on the expression.
This is ground work to:
* Cleaning up the HLSL uniform buffer indexing, which is `/` and `%` arithmatic heavy
* Prepares us to handle `constexpr` when it lands in the spec
* Provide a centralized place to do constant evaluation, instead of the
having similar logic scattered around the codebase.

Copy all of the type classes from src/type into ast.
Required the merging of:
* type::Struct into the existing ast::Struct - ast::Struct now has a name.
* type::AccessControl into the existing ast::AccessControl enumerator - The old ast::AccessControl enumerator is now ast::AccessControl::Access
