fix: make CI pass with the next version of Bazel (9.0.0rc1) (bazel-contrib#3393)

Explicitly load CcToolchainConfigInfo in the fake cc toolchain config.

For examples/bzlmod, bump rules_rust to a newer version so that it pulls
in dependencies that work correctly with Bazel 9.0.0rc1.

Work towards bazel-contrib#3392

(cherry picked from commit 49b6630)
