Jim Graham 0b6d9a337c Reland "add non-rendering operation culling to DisplayListBuilder" (#41463) (flutter/engine#42584) 
This reverts commit 01aeff259a.

Fixes https://github.com/flutter/flutter/issues/125338

This PR should fix the blendmode/color analysis that caused failures for https://github.com/flutter/engine/pull/41463 as well as the bounds failures for inverted rectangles that caused failures for https://github.com/flutter/engine/pull/42330 (incorporating the fix from https://github.com/flutter/engine/pull/42556).

The description from the [previous PR](https://github.com/flutter/engine/pull/41463) updated with the new name of the DL property:

---------------------------------
This optimization avoids recording unnecessary render operations that will not affect the output and also eliminates the need for "draw detection" mechanisms like `DlOpSpy` and `CanvasSpy` by remembering if any non-transparent operations were included. The `DlOpSpy` unit tests were updated to check if the results from that object match the new `DisplayList::modifies_transparent_black()` method.

Fixes https://github.com/flutter/flutter/issues/125338

In addition, this change will unblock some other Issues:

Flow

Flow is a simple compositor based on Skia that the Flutter engine uses to cache recorded paint commands and pixels generated from those recordings. Flow runs on the raster thread and uploads information to Skia.
