tint: Rework tint::Manager

Browse Source 
Don't use dynamic casting in hashing and equality. These should be fast, and dynamic casting is expensive.

Add type::UniqueNode for things that need de-duplicating and bin the types on construction.

Replace some use of SFINAE with constexpr.

Also fixes a build failure for x86.
