Due to #69707 the SkSL tests need the process killing logic still.

This reverts commit 406ca0bc.

My yearly pass to fix spelling errors in the API dartdocs.

* [devicelab] work around occasional null values for devtools

* Update perf_tests.dart

* [flutter_tools] remove iOS screenshot on failure functionality

* remove all screenshot code

These devicelab tests are incredibly flaky. Currently they will build & install the same application 15 times. This causes the temp storage to fill up on android, and has a good chance of flaking on iOS due to install issues.

The change from 3 to 15 increased total test time for 2 -> 12 minutes on iOS, or roughly 5 more test equivalents for every single iOS test. Reduce the iteration count back to 5

Uninstall the app after each run so temp storage does not fill up.

Fixes #67370

By running most of these executions through flutter, we get the benefit of the flutter error handling and precaching. IN the test where this is not feasible, call pre-cache directly.

Removes one-off handling for defines test and forces it to run through the DriverTest interface

Split the integration_ui target into individual driver tests. Remove disabled screenshot tests

Remove devicelab specific code for shutting down gradle daemon, add --android-gradle-daemon option to build/run/drive`. Avoids need for un-tested devicelab specific handler. There are also some feature requests for this, so 2 birds one stone.

Example:

flutter build apk --no-android-gradle-daemon will pass --no-daemon on to gradle
