nir: Validate nir_tex_instr::dest_type bitsize
In theory, we could also verify this against the sampler type for sampler derefs, but there are a number of complications there: - SPIR-V 1.4 lets you override the signedness of integer samplers per-instruction. So the base type may not match. - mediump/RelaxedPrecision samplers may get lowered to f16 in the instruction or may not. So the bitsize may not match.
