As of Bazel 6.0.0, all Bazel-provided toolchains report consistent
compiler names that can be matched on with `select`. Having a central
place for `config_setting`s that can be used for this purpose makes it
so that rulesets don't have to define them themselves and moving the
compiler flag out of `@bazel_tools` becomes easier as it is no longer
referenced directly.
Also includes minor fixes to `//tests/...` so that it can be enabled in
CI.
Right now there should be no difference between `cc_host_toolchain_alias` and `cc_toolchain_alias` rules.
This is a potentially breaking change for Bazel, if something was depending on `current_cc_host_toolchain` try depending on `current_cc_toolchain` instead.

Remove redundant tags for copybara to replace labels with labels including the
repository, where there are no labels to substitute after 2f8c04c044.

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.

Simplify WORKSPACE setup and update ancient deps
By removing a single unused `bzl_library` target, rules_cc no longer has
any dependencies that would need to be loaded by a dependency macro. The
existing macro is made a no-op.
The few needed Bazel Federation dependencies are inlined and, in the
case of bazel_skylib and abseil-py, updated to modern versions.
Also reorders `WORKSPACE` to list direct dependencies first and keeps
`MODULE.bazel` in sync with the dependency versions used in WORKSPACE.
The `ubuntu1604` CI pipeline is removed as the version of Python used by
it is no longer supported and the distribution is EOL. Instead, a new
pipeline is added to check the Bzlmod build.
