What does this bot do?

Builds the Android AAR archive (for use as an SDK library in Android Studio etc)

Instead of adding a new bot for this I think we should just add this to the Android Release bot (and android_rel) trybot. Since those tests are executed in Swarming, the building machine is usually sitting idle waiting for the swarming jobs to execute (except running the android_junit_tests, which is very quick). Then we could just run the archive script. Preferably without using a temp folder (which is the current default) so we'd benefit from incremental builds.

That will be fast except in the cases where all Android tests are returning from cached results (i.e. a binary with the same sha1 hash had already run), but I think that's pretty uncommon.

WebRTC: Retire Android Archive bot and add step to one Android commit+trybot.

The running of https://webrtc.googlesource.com/src/+/master/tools_webrtc/android/build_aar.py
is now added as a new step on:
* Android32 (M Nexus5X) in client.webrtc
* android_rel in tryserver.webrtc

The only change from where it ran before is that for the trybot, --build-dir is passed
so it can benefit from incremental builds (for speed). The regular commit bot always
does a clean build in a temp dir to ensure no undesired old objects are packaged.

WebRTC: Move .aar and AppRTC build+upload to after triggering of tests

As of https://chromium-review.googlesource.com/c/chromium/tools/build/+/689517/8
the build and upload of the Android .aar file takes place before
the swarming tests are triggered. This is wasting a lot of time
blocking the bot. These steps should take place after the
swarming tests have been triggered, for shorter build cycles.

This change also moves the AppRTCMobile upload to take place after
the test tasks are triggered.
