Tint: Refactor transform VertexPulling and its unit tests
This CL prepare transform VertexPulling and its unit tests for
implementing f16 pipeline io. This CL distinguishes vertex format type
and WGSL variable type of a vertex shader attribute (location input) in
VertexPuilling transform as both `f32` and `f16` WGSL types would be
mapepd to float vertex format. This CL splits VertexPulling unit tests
by base veretx format (SInt, UInt and Float), make it easier to add
`f16` tests.
