This CL implements f16 in uniform and storage address space, allowing
using f16 types in uniform and storage buffers on all backends. Tint
uint tests and Dawn E2E tests are added to validate the f16 types work
as expected.

This CL refactor unittests in std140_test.cc, and add exhaustive
parameterized unittests in std140_exhaustive_test.cc. In std140_test.cc,
only test Std140 transform result for `mat2x2<f32>` for matrix used as
array element type and `mat3x2<f32>` otherwise, and keep the source and
expected programs as plain WGSL code to ensure the readablity. In
std140_exhaustive_test.cc, all matrix shape and different constant index
are tested using parameterized WGSL code, at the cost of readablity.
This CL prepares for supporting f16 in Std140 transform by allowing
testing all shape of f16 matrix as well by simply adding parameters.
