i965/nir/vec4: Implement pack/unpack operations

* Lowered floating-point pack and unpack operations are not valid in VS.

* Pack and unpack 2x16 operations should be handled by lower_packing_builtins.

* Adds NIR ALU operations:
   * nir_op_pack_half_2x16
   * nir_op_unpack_half_2x16
   * nir_op_unpack_unorm_4x8
   * nir_op_unpack_snorm_4x8
   * nir_op_pack_unorm_4x8
   * nir_op_pack_snorm_4x8
