Brandon DeRosier 30fe68f402 [Impeller] Don't cull readbacks outside the damage rect. (flutter/engine#46705) ...

Resolves https://github.com/flutter/flutter/issues/136058.

The damage rect properly expands to include the backdrop filter readback area to a certain extent, but it suddenly gets excluded once it no longer partially overlaps with the damage rect. This caused the illusion of EntityPass improperly culling the backdrop entity, leading me into a bit of a wild goose chase.
