Some of the IR classes require setters in order to update dependant
information. In order to keep the IR access symmetrical this CL moves
the IR back to using accessors and private fields.

For the `if`, `switch` and `function` flow nodes this Cl makes a few
required fields part of the constructor. This cuts down boilerplate when
creating new nodes.

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.
