Profile includes can be setup to loop and expand in a pathalogical
manner that causes build failures. Fix this by caching which includes
have already been seen in a given profile context.
In addition this can speed up some profile compiles, that end up
re-including common abstractions. By not only deduping the files
being included but skipping the need to reprocess and dedup the
rules within the include.
