remove false OnBlockAdded dependency on phase0 HashedBeaconState (#2661)
* remove false OnBlockAdded dependency on phase.HashedBeaconState

* introduce altair data types into block_clearance; update some alpha.6 spec refs to alpha.7; add get_active_validator_indices_len ForkedHashedBeaconState wrapper

* switch many modules from using datatypes (with phase0 states/blocks) to datatypes/base (fork-independent); update spec refs from alpha.6 to alpha.7 and remove rm'd G2_POINT_AT_INFINITY

* switch more modules from using datatypes (with phase0 states/blocks) to datatypes/base (fork-independent); update spec refs from alpha.6 to alpha.7

* remove unnecessary phase0-only wrapper of get_attesting_indices(); allow signatures_batch to process either fork; remove O(n^2) nested loop in process_inactivity_updates(); add altair support to getAttestationsforTestBlock()

* add Altair versions of asSigVerified(), asTrusted(), and makeBeaconBlock()

* fix spec URL to be Altair for Altair makeBeaconBlock()
