Fixes:
* Enabled buildifier on the Bazel CI again
* Added Skydocs where missing
* Moved public files out of .../private/... (e.g. cc_toolchain_config_lib.bzl)
* Reformatted
* Removed unused loads
* Using relative labels for cc_configure related files
* Added development dependency on rules_proto
* they're not in the federation yet, so hand rolling in rules_cc's WORKSPACE file
* Added development dependency on rules_python (from federation)
* Cleaned up copybara (notable change - not using @rules_cc in labels inside rules_cc repo)
* Made cc_flags_supplier usable internally
* Moved load statements to the top of the bzl file
* Moved runfiles to the tools directory
* Unified toolchain_utils.bzl and find_cc_toolchain.bzl

Here we are duplicating bazel_tools/tools/cpp. The goal is for the BUILD files in bazel_tools/tools/cpp to have an alias that point to rules_cc. Then later on with the incompatible flag these aliases will no longer be valid.
Working towards #8743

In order to migrate C++ rules to platforms, we need the access to the C++
configuration fragment in Starlark APIs. All existing APIs have already access
to it, but cc_common.configure_features doesn't. This change adds a
ctx argument to configure_features.
This is the migration needed for
https://github.com/bazelbuild/bazel/issues/7793, and is part of the effort for
https://github.com/bazelbuild/bazel/issues/6516.
If the rule doesn't depend on cpp fragment yet, you will have to add `fragments
=['cpp']` argument to the rule() call.
Note that this behavior is only available in Bazel 0.25 (to be released this month).
