A few additional Androix dependencies

[edman]

Apparently some dependencies like android.support.annotation were implicitly available, but that doesn't seem to be true anymore with AndroidX.

Tracked in flutter/flutter#23995.
Related to #1115

By the way, since AndroidX migration is a breaking change shouldn't we update the major version of affected libraries to respect semantic versioning?

Hi @mklim, could you have a look at this PR? I needed to make these changes to get your AndroidX migration working in my machine.

Thanks for the PR, really appreciate it. I can't reproduce any problems from not including these dependencies, but I don't think having the implicit deps is great in the first place and I'm not seeing any additional problems from adding them explicitly.

Yes. That was a terrible mistake, since been reverted and forward rolled with the right major versioning. Pub treats different digits as "major" depending on whether the package is at or below 1.0.0, and the original PRs didn't differentiate correctly between the packages.
