Numerous tools override --custom_malloc to add debugging or monitoring runtimes
(see e.g. sanitizers). While this is fine for cases where the tool must also
override malloc to function, in other cases it's simply misuse of
--custom_malloc where no other mechanism exists to link an extra library.
This becomes especially problematic where a runtime library is supposed to be
added in certain configurations that should run in production or other
performance sensitive builds. In these cases, we should _not_ override malloc,
which may also be specified by a cc_binary target. Doing so would introduce
unwanted changes, potentially affecting performance negatively.
This is the @rules_cc counterpart to the equivalent Bazel tools flag
--@bazel_tools//tools/cpp:link_extra_libs. Users that use @rules_cc to build
their C++ projects may use both flags interchangably, however, the @rules_cc
flag should be preferred.

When adding tags to a native cc_library rule that is created through a macro we
were not properly considering the case where the tags came from a different
file and therefore were frozen. This caused an error.

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.
