John Stiles 712fd6bbb9 Add support for enums in Metal code generator.
Enums are an SkSL-only concept--when we output code, we emit plain
IntLiterals--so the fix is simply to ignore the Enum program element
when we encounter it. This is what GLSLCodeGen does as well.

Also added a unit test to confirm that enums work normally, and that
enums are subject to optimization and static-comparison checks just as
ints would be.
