Expose an API for calculating catcache hash values. Now that cache invalidation callbacks get only a hash value, and not a tuple TID (per commits 632ae6829f7abda34e15082c91d9dfb3fc0f298b and b5282aa893e565b7844f8237462cb843438cdd5e), the only way they can restrict what they invalidate is to know what the hash values mean. setrefs.c was doing this via a hard-wired assumption but that seems pretty grotty, and it'll only get worse as more cases come up. So let's expose a calculation function that takes the same parameters as SearchSysCache. Per complaint from Marko Kreen.
