Delete DB schema migrations for v11 and earlier (#3761)

Browse Source 
## Proposed Changes

Now that the Gnosis merge is scheduled, all users should have upgraded beyond Lighthouse v3.0.0. Accordingly we can delete schema migrations for versions prior to v3.0.0.

## Additional Info

I also deleted the state cache stuff I added in #3714 as it turned out to be useless for the light client proofs due to the one-slot offset.
