This allows setting GCOV on the command line to overwrite the default setting, which points to /usr/bin/gcov. In order to use this, you also need to disable the gcov coverage feature and enable the llvm coverage feature instead. The full command-line looks like this:
GCOV=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/llvm-profdata bazel coverage --features=llvm_coverage_map_format --features=-gcc_coverage_map_format //cpp:test
Progress on #10457.

Default linker flags contains flags like -lstdc++ which should come after the
user libraries. The library flags are removed from default linker flags and added to link_libs instead which comes after user libraries.
See #9254

I introduce a new method to repositories ctx that allows checking the value of a Starlark semantic option from a repository rule.

For now we will restrict allowed exports to the same package. At the same time
static_deps should be used to take into account what should be linked into a
shared library.

We're working on removing C++ toolchain autoconfiguration logic out of Bazel,
and moving towards using rules_cc repository for it. Some bzl files will no
longer be available through bazel/tools/cpp/*, but through
@rules_cc/cc/*.

Labels in toolchains attribute need to include the repository, otherwise the resolution won't work.

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

BEGIN_PUBLIC
Remove unused load statements from .bzl files
After transitive loads have been disabled in Blaze, unused load statements have
no effect (besides not useful memory consumption).
The CL has been created automatically by calling `buildifier --lint=fix --warnings=load` on all .bzl files.
The following additional command were run on all affected files to clean them up:
* buildifier -a -v --lint=fix --warnings=load-on-top
Moves all load statements to the top of a file
* buildifier -a -v --lint=fix --warnings=same-origin-load
Compresses all load statements from the same .bzl file to one load statement

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.
