John Stiles 34de5cb57b Convert remaining Metal tests to golden outputs.
Metal-specific tests are pretty thin on the ground here, and some of
the remaining tests no longer added value as they were already covered
pretty well by existing tests in Shared. The majority of remaining tests
were specific to Metal's lack of flexible matrix casting (and SkSL's
ability to paper over this with helper functions).
