Eitan Seri-Levi f818612795 fix: remove premature on_valid_payload_envelope_received + disable backfill for GLOaS
1. Remove on_valid_payload_envelope_received call before process_block
   in chain segment import. The block isn't in fork choice yet, so it
   always fails with NodeUnknown. import_envelope_from_range_sync
   handles this correctly after process_block.

2. Disable backfill sync when GLOaS is scheduled. Backfill calls
   into_available_block which panics on GLOaS RangeSyncBlock variant.
   Backfill for GLOaS is not yet implemented.
