[scenic] Add simple pixel tests

Adds two tests:

* Renders a solid color. All pixels are asserted to be this color.
* Renders a static square. Screenshot is saved to a file for consumption by
  Skia Gold (integration to come later; this does not yet do a diff).

This test only executes on hardware (see changes to bin/ui/BUILD.gn).

Test: fx run-test scenic_tests -t gfx_pixeltests
      Replaced solid color with square to verify failure case.
