fix: add use_repo for local_config_cc to enable C++ toolchains

The key fix for C++ toolchain resolution was adding:
- use_repo(cc_configure, "local_config_cc")

This ensures @local_config_cc repository is available for building
Rust binaries that require C++ linking, resolving the persistent
'No matching toolchains found for @@bazel_tools//tools/cpp:toolchain_type' error.
