fix(rpc-types): replace uint and hash with ethereum_types v0.4 (#10217)

* fix(rpc-types): remove uint and hash wrappers

* fix(tests)

* fix(cleanup)

* grumbles(rpc-api): revert `verify_signature`

* revert change of `U64` -> `u64`

* fix(cleanup after bad merge)

* chore(bump ethereum-types)

* fix(bad merge)

* feat(tests ethereum-types): add tests

* chore(update `ethereum-types` to 0.4.2)

* feat(tests for h256)

* chore(rpc): remove `ethbloom` import

Use re-export from `ethereum-types` instead

* fix(bad merge): remove `DefaultAccount` type

* doc(add TODO with issue link)
