Reverts flutter/flutter#142062 Initiated by: eliasyishak This change reverts the following previous change: Original Description: This PR makes no _behavioral_ changes to executed code, and instead focuses on organization and naming: 1. Almost[^1] anything named `external_ui` is renamed `external_textures` 1. Extended the README to explain the intent of the test, as well as how to run it 1. Renamed `main.dart` and `main_test.dart` to `frame_rate_main.dart` and `frame_rate_test.dart` (we'll add more) 1. Did some refactoring of the test to make it more obvious what is being asserted (i.e. `widgetBuilds` and friends) Given how complex (and in-flux) this directory is, I'm also requesting either John, Jonah or I review any changes. [^1]: Except the name of the `.ci.yaml` task, i.e. `name: Linux_pixel_7pro external_ui_integration_test` because I'm apparently not able to change that without creating a new task as `bringup: true` and playing a bit of a dance. Maybe that's worth doing though (in future PRs)?
