[NFCI] Deduplicate builtin FF cell types list
A few passes included the same list of FF cell types. Make it a global
const instead.
The zinit pass also seems to include a list like that, but given that
it seems to be completely broken at the time (see #1568 discussion),
I'm going to pretend I didn't see that.
