* Disable failing test due to SDK issue

* Disable failing debugger and hot reload windows tests

In principle this is backwards compatible; I just merged all the classes into one and deprecated everything that became redundant as a result.

[flutter_tools] use initially parsed package config for language version, sound mode determination (#70323)

Revert "[integration_test] Add a `run` method for proper reporting of test results (#70075)" (#70466)

This reverts commit af5eb3b9.

Change the semantics of Actions.invoke so that if the action it finds is disabled, then it keeps looking for an ancestor Actions widgets that has a matching intent where the action is not disabled.

[flutter_tools] remove branch migration and standardize constructor style for version interface (#70058)

Migrate flutter_localizations to null safety.

This reverts commit a0ec4d67.

Unit tests that cover their translations are also added.

This allows the two videos in the demo to play simultaneously
(matching the behavior from before the recent upgrade to the
video player plugin)

This reverts usages of the binding's platformDispatcher to use window again temporarily, because there isn't a TestPlatformDispatcher yet, and so some tests were failing because they mocked the TestWindow to return certain things (locales) that were returning the real values instead of the test values.

Once I've created a TestPlatformDispatcher to allow fake data to be passed to it, we can go back to using the platformDispatcher in all of these places

This reverts commit 1f0df545.

This reverts commit 15d2d8a8.

* Move web integration tool tests to web.shard

Web integration tool tests depend on DDC changes in SDK. This change
moves them to a separate shard and subshard so CI bot configurations
can run them separately.

In particular, with will allow running those tests on dart CI flutter
HHH web bot instead of a non-web one, allowing early detection and easy
classification of issues caused by SDK changes as VM- or Web related.

* Enabled verbose mode for flaky web_tool_tests

* Split out the test changes to be commited first
