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).

msl: Promote local private vars to function scope If a module-scope private variable is only referenced within a single function, promote it to a function scope declaration instead of passing it as a parameter. This reduces the number of a function parameters that are needed in some cases.
