gs101: Use SkiaGL as RenderEngine backend

This reverts commit 6968365b28142e601a8d65575ad9f7c76208773c.

Reason for revert: b/281967184 and b/280343156

Even though using SkiaVK with RenderEngine has definite benefits, it appears to need more "soak time" in order to squeeze out some functional bugs.

Test: none-returning RenderEngine to using SkiaGL, as it was before
Bug: 281967184
Bug: 280343156
