Do not add spirv::BitcastOp for cast from signed to unsigned type.

Since MLIR integer types don't make a distinction between signed vs
unsigned integers, during deserialization of SPIR-V binaries, the
OpBitcast might result in a cast from/to the same type. Do not add a
spv.Bitcast operation to the spv.module in these cases.
