[SPARK-18640] Add synchronization to TaskScheduler.runningTasksByExec…
…utors ## What changes were proposed in this pull request? The method `TaskSchedulerImpl.runningTasksByExecutors()` accesses the mutable `executorIdToRunningTaskIds` map without proper synchronization. In addition, as markhamstra pointed out in #15986, the signature's use of parentheses is a little odd given that this is a pure getter method. This patch fixes both issues. ## How was this patch tested? Covered by existing tests. Author: Josh Rosen <joshrosen@databricks.com> Closes #16073 from JoshRosen/runningTasksByExecutors-thread-safety. (cherry picked from commit c51c772) Signed-off-by: Andrew Or <andrewor14@gmail.com>
