[ir][spirv-writer] Expand implicit vector splats

Add a new transform that looks for implicit vector splats in construct
or binary instructions and expands them to be explicitly constructed
vectors instead.

Add an intrinsic for OpVectorTimesScalar and use that for the floating
point vector * scalar case, instead of pattern matching in the writer.
