nir/alu_to_scalar: Use ssa_for_alu_src in hand-rolled expansions
The ssa_for_alu_src helper will correctly handle swizzles and other
source modifiers for you. The expansions for unpack_half_2x16,
pack_uvec2_to_uint, and pack_uvec4_to_uint were all broken with regards
to swizzles. The brokenness of unpack_half_2x16 was causing rendering
errors in Rise of the Tomb Raider on Intel ever since c11833ab24dcba26
which added an extra copy propagation to the optimization pipeline and
caused us to start seeing swizzles where we hadn't seen any before.
