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.

a88b63d83c Ensure FoldMap always contains at least one transform 
Previously, when splicing an edit that deleted all transforms, we would
leave the `FoldMap` empty, thus violating a bunch of downstream
invariants and e.g. causing the `BufferRows` iterator to not return any
buffer row.

This commit ensures we always have at least one transform (an isomorphic
one, specifically) and adds additional test coverage for the
`FoldMap::buffer_rows` method by adding it to the randomized tests.

2c24ec2e46 Update old usages of ctx.spawn to detach the associated task

a small bug when rendering the gutter that I am going to fix next.

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.
