Add ctx argument to cc_common.configure_features
Add ctx argument to cc_common.configure_features

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).
