Added support for enabling built-in kotlin.

Currently Flutter disables built-in kotlin by default to give app and plugin developers time to migrate to Built-in Kotlin. Once necessary migrations have been made, app developers should have the ability to opt-into Built-in Kotlin to see if their migrations are valid. As-is builds will break when opted-in to Built-in Kotlin--even if all necessary migrations have been made. So, we must support opting in to built-in Kotlin.

  • Abstracted the parsing and detection of AGP and KGP in build files into a dedicated helper for unit testing. This can help us better debug in case of failure.
  • BuiltInKotlinIsEnabledAndAgpIs9OrHigher only consists of the "good" path where all subprojects have been migrated off of KGP. The "bad" path where Built-in Kotlin is enabled and not all subprojects have been migrated is not captured/tested here because there is an Android error triggered before FGP is applied. This is already handled with a helpful Flutter error leading to Flutter docs.
  • Removed call to get agp version in projectsEvaluated hook because when FGP is invoked, the app's AGP is has already been applied/resolved. (did some testing and works as expected)

Fixes #187712

Pre-launch Checklist

If you need help, consider asking for advice on the #hackers-new channel on Discord.

If this change needs to override an active code freeze, provide a comment explaining why. The code freeze workflow can be overridden by code reviewers. See pinned issues for any active code freezes with guidance.

Note: The Flutter team is currently trialing the use of Gemini Code Assist for GitHub. Comments from the gemini-code-assist bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.
