John Stiles b44185086e Reland "Improve support for arrays in Metal."
This reverts commit 38df4c8470.

Reason for revert: updated ArrayTypes test for ES2 compatibility

> Original change's description:
> > Improve support for arrays in Metal.
> >
> > Arrays in Metal now use the `array<T, N>` type instead of the C-style
> > `T[N]` type. This gives them semantics much more in line with GLSL,
> > so they can be initialized and assigned like GLSL arrays.
> >
> > This allows the ArrayTypes and Assignment tests to pass, so they have
> > been added to our dm SkSL tests. (ArrayConstructors also passes, but
> > is not ES2-compliant so it is not enabled.)
