Include cc configure headers in the cache key

This PR adds a file containing builtin include directories paths as an input to every C++ compilation action. The result is that whenever these headers change (as a result of reconfiguring `cc_configure` repository rule), we include this file in the action cache key.

Fixes https://github.com/bazelbuild/bazel/issues/9296.

Closes #9295.
