env, ci: add support for linux emulator runs, add new emulator modu…

…le (vlang#315)

* android: add `emulator` module

* ci: add `ubuntu-latest` based emulator runs

* ci: add `v retry -r 2 --` to AAB deployments as these are sometimes flaky

* env: support installing `system-images`

* ci: simplify caching, do not cache test avd (not really time consuming)
