Revert AndroidX changes for 1.0.0 plugins (#1127)

The AndroidX migration didn't increment the major version for plugins >=
1.0.0. This commit reverts the code changes in the affected plugins.

It's critical that the forward roll PR is published with this so that clients
that have previously migrated aren't broken by the revert. I'm not planning
on merging this into master until the forward roll (flutter/plugins#1128) is
also LGTMed and ready to merge.
