Provides the currently active Python toolchain's C libraries.

This is a wrapper around the underlying `cc_library()` for the
C libraries for the consuming target's currently active Python toolchain.

To use, simply depend on this target where you would have wanted the
toolchain's underlying `:libpython` target:

```starlark
cc_library(
    name = "foo",
    deps = ["@rules_python//python/cc:current_py_cc_libs"]
)
