Consolidate 2d.layer.global-states tests into fewer files
All 2d.layer.global-states tests currently pass with exact pixel values
in Chromium. We can pack them into grids, using significantly fewer
files. We can easily break the grids back to using different files if
needed, for instance, if WebKit later finds that only some tests in the
grid are failing.
Unfortunately, the WPT test runner takes 800x600 screenshots which is
not large enough to hold all tests in a single grid. For that reason,
the no-transform/rotation dimension uses different files.
