Try to workaround OOM errors and the runners dying (#3013)

* Try to workaround OOM errors and the runner dying

* Some more tweaks:

- Add `-XX:MaxMetaspaceSize` (https://github.com/gradle/gradle/issues/19750)
- Remove `-PpreDexEnable` as it's deprecated and no longer used.
- Remove `--max-workers` as gradle will automatically use the optimal amount.

* Remove `--max-workers` in recording screenshots too
