#142464 reverts logic in flutter.groovy in order to fix #141940, but in the process, has removed some logic required to add support for the Gradle Kotlin DSL that was added in #140744. This issue serves as a reminder to re-land this logic to maintain that support.

This involves two steps:

• Replace the old implementation of doesSupportAndroidPlatform with the new implementation created in Add support for Gradle Kotlin DSL #140744.
• When Reland: "Fix how Gradle resolves Android plugin" #137115 is re-landed, add back logic that checks for Gradle settings configuration for both Groovy or Kotlin
