Improve GRADLE build Performance

[ChenZhangg]

Parallel test execution maxParallelForks, running multiple test cases in parallel is useful and helpful when there are several CPU cores.

According to Process forking options, Gradle will run all tests in a single forked VM by default. This can be problematic if there are a lot of tests or some very memory-hungry ones.
one option is to fork a new test VM after a certain number of tests have run. So our recommendation is to configure "forkEvery" and we give a specific value of 100

Disable report generation, Gradle will automatically create test reports by default which will slowing down the overall build. So it's better to disable the test reports while we don't need it

Incremental compilation, We note that the gradle version for this project is smaller than 4.10, so we recommend enabling this configuration to shorten build times

Thank you for your contribution! As a friendly heads up - as noted in README.md, this repository has been migrated to a self-hosted GitLab instance at https://git.kuschku.de/justJanne/QuasselDroid-ng/ (you can sign in with your GitHub account).

Aside, @justjanne , would it be worthwhile being more bold/upfront about the migration in the README, repo description, etc, then set the repository as archived?
