content_shell is a content embedder and therefore can only include public
headers.

You can add a method to content/public/test/layouttest_support.h (and
content/test/layouttset_support.cc) to forward the call.

Done.

Is this automatically enforced somehow?

sure, via include rules in the DEPS files.
