Clean up Bazel workspace rules

  * Migrated most WORKSPACE deps to MODULE.bazel (will be required in Bazel 9.x).
  * Use `.bazelversion` to declare Bazel version instead of `USE_BAZEL_VERSION`
    env variable (makes it easier to run locally with same bazel version).
  * Explicitly set `source`/`target` for `dagger.android` api, and use
    `.bazelrc` to set default `source`/`target` for annotation processors.
  * Removed unused bazel common dependencies in WORKSPACE
     * Removed `bazel_skylib`
     * Removed `google_bazel_common`
     * Removed `rules_python`
     * Removed `zlib`
  * Removed obsolete `tools/bazel.rc` config
