Ben Clayton 7103f51603 writer/msl: Fix swizzling on packed vectors
Metal 1.x does not support swizzling on packed_vec types.
Use array-index for single element selection (permitted on LHS and RHS of assignment)
Cast the packed_vec to a vec for multiple element swizzles (not permitted as the LHS of an assignment).

Fixed: tint:1249
