We have been transitioning the depth/stencil atttachment to general, even though it can just be in attachment optimal (we never use it as an input attachment).

Fixes flutter/flutter#145823

If we try to render a solid filled empty size path, the subpath division code creates an obscene number of vertices that hits overflow errors. Just No-op instead.

This reverts commit 73c145c.

Attempts to improve flutter/flutter#145274.

Our new clipping technique paints walls on the depth buffer "in front" of the Entities that will be affected by said clips. So when an intersect clip is drawn (the common case), the clip will cover the whole framebuffer.

Depth is divvied up such that deeper clips get drawn _behind_ shallower clips, and so many clips actually don't end up drawing depth across the whole framebuffer. However, if the app does a lot of transitioning from a huge clips to a small clips, a lot of unnecessary depth churn occurs (very common in Flutter -- this happens with both the app bar and floating action button in the counter template, for example).

Since progressively deeper layers in the clip coverage stack always subset their parent layers, we can reduce waste for small intersect clips by setting the scissor to the clip coverage rect instead of drawing the clip to the whole screen.

Note that this change _does not_ help much with huge/fullscreen clips.

Also, we could potentially improve this further by computing much stricter bounds. Rather than just using clip coverage for the scissor, we could intersect it with the union of all draws affected by the clip at the cost of a bit more CPU churn per draw. I don't think that's enough juice for the squeeze though.

We don't intend to make much progress on the Impeller OpenGLES backend in 2024. I won't remove the capability to run these tests locally (the plumbing is already done and doesn't cost anything), but we don't need to have these just sit/flake on CI consuming resources.

Partial work towards flutter/flutter#144064.
