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

This reverts commit ddab72e7.

* Revert "Revert "Improve performance of collectAllElements (#68065)" (#68207)"

This reverts commit 46ff57d6.

* use fewer elements for benchmark

[devicelab] allow the devicelab to take a screenshot if the iOS connection fails with FLUTTER_IOS_SCREENSHOT_ON_CONNECTION_FAILURE (#68156)

More attempts to remote diagnose the issues in the iOS devicelab

This crash affects anyone using flutter, so move it into the tool where it can be tested and documented. Ensure it works on windows devicelab too.

This reverts commit 8ba5732c.

- run_without_leak_tests: have been disabled for months
- build_benchmark: the tooling work here is mostly done and we're not tracking further improvements, free up more devicelab capacity
- system_debug_ios: does not work post iOS13
- mac_enable_twc: not adding more mac tests to devicelab
- hello_world_start_up: disabled

Any tests that we think will be valuable in the future can be resurrected from the git history.

--use-application-binary allows running with an already built APK. This can be useful for speeding up CI test cases, or in our case eventually supporting some sort of build server. Demonstrate that this works by updating the old gallery test to use it. Fixes #56604

A change which sped up hot restart locally caused many of the devicelab measures to regress. I think this is because we do not measure when the isolate is actually "ready", so starting a reload or restart prematurely can cause time spent doing initialization to be registered as part of the reload operation.

A fix for this would be to have the framework include some sort of "initialization complete" event ... but it is not clear what the correct trigger would be. Perhaps after the first frame is successfully registered?

(9a3a0dc1 caused the benchmark regression - possibly since we spend less time syncing files now so we start the restart earlier)

The previously broken test should be fixed by
https://github.com/flutter/gallery/pull/331

This reverts commit 2d9e5005.

In addition, this fixes broken Android tests of the original PR.

This reverts commit 2ae09caa.

This shouldn't break our tests as
https://github.com/flutter/gallery/issues/275 is closed.

This reverts commit 48ce83a8.
