RFR 8228675: Resolve.findMethod doesn't cache interface type calculation

Fair question.

github.com/google/dagger generates implementations of interfaces that
implement a dependency injection graph. Sometimes, though not always, these
interfaces have dozens if not hundreds of (super)interfaces which allow for
builds to be sharded: each subsection of the build refers to the
superinterface and then at the root of the build there is a union of them
all. Naturally, this means this must be rebuilt on most/all changes to any
subproject of the build.
