Speed up CI (com-lihaoyi#4442)
* Increase `-j` parallelism to 0.75C to try and saturate the CPU * Move android parallelism limit out of `action.yml`, where the `if` condition was for some reason not evaluating properly * Split up some big integration suites to take advantage of `testForkGrouping` Fixes com-lihaoyi#4440. Manually looked at the CI logs to see that the test command is now running without `-j1` and the status ticker is showing multiple tasks running at once --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
