Add find_cc_toolchain.bzl to help accessing current C++ toolchain

This is to help migrating for:

* https://github.com/bazelbuild/bazel/issues/7260
* https://github.com/bazelbuild/bazel/issues/7643

It's mostly a copy of the file in
`@bazel_tools//tools/cpp:toolchain_utils.bzl`, with a small difference -
it depends on `@rules_cc//cc:toolchain_type`, not on
`@bazel_tools//tools/cpp:toolchain_type`.
