Tint/tranfsorm/test: Refactor and add exhaustive test for Std140

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.
