Release 5.0.0-pre.20210824.2 (2021-08-27)

Baseline: 19ae197

Cherry picks:

   + 18bfed2:
     Properly preserve state when interrupted during a deletion. Also
     use best Bazel practices for reinitializing maps by reassigning,
     since just clearing can retain memory. When enqueuing deleted
     nodes, don't use more threads than there are nodes. Finally, fix
     a test accidentally changed in
     3ea75594bfdb5e67942501
     55995c45a5adc00c28.

Incompatible changes:

  - Flipped --incompatible_disallow_resource_jars (see
    #13221).

Important changes:

  - Disable --all_incompatible_changes flag.

This release contains contributions from many people at Google, as well as Benjamin Peterson, Ben Lee, Grzegorz Lukasik, Ikko Ashimine.
