[Reland] Add migrator to upgrade gradle version when conflict with Android...

[Reland] Add migrator to upgrade gradle version when conflict with Android Studio bundled Java version is detected (#125836)

This is an attempt to reland https://github.com/flutter/flutter/pull/124085.

Differences from this attempt and the last: 
1. Adds a check for null android studio versions and a test for this case.
2. Wraps the migrate code in a try-catch [per the suggestion here](https://github.com/flutter/flutter/pull/125728/files#r1181747899).

Old PR description:
This PR adds an android project migrator that checks the version of android studio and the version of gradle for conflicts, and upgrades to 7.4 if a conflict is detected. For more detail about the particular conflict, see https://github.com/flutter/flutter/issues/122376.

The PR also upgrades older gradle versions being used in integration testing to 7.4.

Fixes/related to: https://github.com/flutter/flutter/issues/122376 and https://github.com/flutter/flutter/issues/123636
