  - Running Doclava in parallel with other tasks via the Gradle Worker API
    
    So that starting to run dokka doesn't need to wait for doclava to complete
    
    On my computer, this reduces the time to run `./cleanBuild.sh -y zipDoclavaDocs zipDokkaDocs`:
      from 9m52s
      to   8m59s
    
    Bug: 175149111
    Test: ./cleanBuild.sh -y zipDoclavaDocs zipDokkaDocs
    Test: Treehugger runs busytown/androidx.sh
    
    Note that this change is similar to aosp/1161553 ; that knowledge could make it easier to review

  - Running doclava via javaexec rather than javadoc
    
    in preparation to invoke Doclava via the Gradle Worker API, which allows multiple tasks in one project to execute at once.
    
    Bug: 175149111
    Test: Run `./cleanBuild.sh -y zipDoclavaDocs` before and after this change, unzip the resulting zips (out/dist/doclava-public-docs-0.zip and out/dist/doclava-tip-of-tree-docs-0.zip), and see that their contents didn't change
    
    Test: Treehugger runs busytown/androidx.sh
