This CL adds a TypedInteger helper which provides additional type
safety in Dawn. It is a compile-time restriction that prevents integers
of different types from being used interchangably in Debug builds.
It also adds ityp::{array,bitset,span} as helper classes to wrap std::
versions (not span). These accept a template paramter as the Index type
so that typed integers, or enum classes, may be used as a type-safe
index.
For now, bind group layout binding indices use TypedInteger. Future
CLs will convert other indices to be type-safe as well.
