Introduce RuleKeyBuilderFactory so that all RuleKeys can be seeded with common data.

Summary:
Ultimately, we need to be able to include build options from `.buckconfig` in the
computation of a `RuleKey`. (It would also be nice to be able to inject it for
testing purposes.)

Test Plan: Sandcastle builds.
