This PR also adds transitive dependency on  web_socket_channel, crypto, typed_data. `web_socket_channel` is needed to request retaining path for not GCed objects from VM Service. Two others are needed to serve web_socket_channel.

The dependency on leak_tracker is pinned:

New feature in upcoming Dart 3.2. See https://github.com/dart-lang/language/issues/2020. Feature is enabled by bumping the min SDK version to 3.2.

Part of https://github.com/flutter/flutter/issues/134476.

Unpins path_provider_android where it is pinned. Follows the same steps as https://github.com/flutter/flutter/pull/128898.

Fixes https://github.com/flutter/flutter/issues/116376

Unpins flutter_plugin_android_lifecycle where it is pinned. I then 
1. ran `flutter update-packages --force-upgrade` (but only committed the changes within `dev/integration_tests/gradle_deprecated_settings/`, which is where it had been pinned) 
2. followed by `./gradlew :generateLockfiles` from `dev/integration_tests/gradle_deprecated_settings/android/` (the lockfile was what was causing the CI dependency resolution failure, so this second step is the fix for that).

See the reason it was pinned: https://github.com/flutter/flutter/pull/121847#discussion_r1124797112 followed by the PR that pinned it: https://github.com/flutter/flutter/pull/122043

Fixes https://github.com/flutter/flutter/issues/122039

camera_android was pinned because of https://github.com/flutter/flutter/issues/126710, which was fixed upstream in release 0.10.8+1.

Fixes https://github.com/flutter/flutter/issues/126259
