Release 6.0.0-pre.20220720.3 (2022-08-02)

Baseline: 4cd266aa1dfa53d8c8de44f7895edcfd46f74725

Cherry picks:

   + f706da832996ab30ddd8784f2af697a3bb62852b:
     Requires delayed release

Important changes:

  - Added new register_{execution_platforms,toolchains} directives to
    the MODULE.bazel file, to replace the
    {execution_platforms,toolchains}_to_register attributes on the
    module() directive.
  - The legacy pkg_tar no longer supports the ability to untar and
    repackage an input tar file (`deps` attribute). Users needed that
    capability must switch to github.com/bazelbuild/rules_pkg.

This release contains contributions from many people at Google, as well as Emil Kattainen, Jason Tan, Keith Smiley, Luis Fernando Pino Duque, rustberry, Son Luong Ngoc, Yannic Bonenberger, Yannic.
