Allow sending Altair blocks to /eth/v1/beacon/blocks (#9685)
* Allow sending Altar blocks to `/eth/v1/beacon/blocks`

* tests

* add documentation

* fix ineffectual assignment

* change type of sync committee bits

* remove unused import

* fix Altair epoch calculation

* compare slot against slot

* do not publicly export E2E constant

* tests for setInitialPublishBlockPostRequest
