Add C++ aliases for the wgsl types `i32`, `u32` and `f32`. Separate types out from the builder and into a `Builder::Types` class. An instance of this is now held by the `Builder::ty` field. Makes it clear when you are referencing a `ast::type` instead of a constructor method. Rework a number of builder methods so they take the type as a template argument instead of a parameter. This more closely resembles wgsl (example: `vec2<i32>(1,2)`) Use PascalCase for the constructor methods, but keep the wgsl-like constructors lowercase to imitate the language style. Add `BuilderWithContext` so that `Builder` can be truely immutable, and so we can remove `set_context()`.
