Try to detect Gradle error messages that hint at AndroidX problems, and
warn in the logs about the potential problem and point to documentation
on how to fix the issue.

Unfortunately the Gradle errors based on this root issue are varied and
project dependent. It's probably better to still leave the message
intact in case the problem is unrelated.

Also filters out the plugin warning message pending in
flutter/plugins#1138. It's still valuable to add that for people on
previous versions of Flutter, but this link should override that message
for anyone on an up to date version of Flutter.
