This CL moves to having a `FunctionTerminator` and a `RootTerminator` so
we can assert if the IR is in a function depending on the terminator
seen.

The Castable class is used by utils/. This Cl moves the implementation
into the utils/ folder. The `Is` and `As` methods are added into the
`tint` namespace to make usage shorter.

This CL starts adding the basics for an IR for Tint. The IR is
a lower level representation then the AST with several of the
restrictions removed. For example, the IR is mutable, is a DAG
instead of a tree, and removes a number of WGSL constructs to
simplify transforms.
