3bd6b92244 Introduce a GPUI test platform, get most tests running 
There are still two tests that don't pass:
* `gpui::app::tests::test_finish_pending_tasks` hangs
* `editor::buffer_view::tests::test_fold` has an assertion failure

97e0db205d Don't blend alpha channels 
We want to use the source alpha to determine the color of the final
pixel, but we want the final pixels to be fully opaque.

4773f5034b Bump max path windings to 128

466016a374 Snap sprites to pixel grid in Renderer 
Previously, we were doing so in the `SpriteCache` but that would cause
floating point errors that caused glyphs to sometimes be positioned
midway through a pixel.
