This is the version mandated by Godot's gradle setup anyway so it would get
installed when running gradlew. Now we pre-install the correct version.
(cherry picked from commit 7eaf4d445d)
This was forgotten when renaming 3.2.4 to 3.3.
Once 3.3-stable is out and we branch off to 3.3, the BASE_BRANCH should
be bumped to 3.3 in that branch.
We often hit "Too Many Requests" errors when uploading the cache with
`actions/cache` because there's a limit of 10 GB every 5 minutes, and we can
easily go over it when we amend or merge several PRs in a short timespan.
This will make the CI artifacts less useful for debugging crashes but there's
no real way around this.
(cherry picked from commit caea551d41)
No need to waste time downloading all this when it's readily available :)
Also use the official action to setup Java 8.
Also build both architectures (armv7 and arm64v8) and generate the APK,
so we can upload it.
Remove now unused and outdated `misc/ci/android-tools-linux.sh`.
(cherry picked from commit 5f19e1d571)
Removes AppVeyor and all Travis jobs but the iOS one, which hasn't been ported
to GitHub Actions yet (should be done soon).
Backports new style scripts from `master` branch too to do the same checks.
