Gloas cold DB (#8991)

Browse Source 
Closes:

- https://github.com/sigp/lighthouse/issues/8958


  - Update the `HotColdStore` to handle storage of cold states.
- Update `BeaconSnapshot` to hold the execution envelope. This is required to make `chain_dump`-related checks sane, and will be generally useful (see: https://github.com/sigp/lighthouse/issues/8956).
- Bug fix in the `BlockReplayer` for the case where the starting state is already `Full` (we should not try to apply another payload). This happens on the cold DB path because we try to replay from the closest cached state (which is often full).
- Update `test_gloas_hot_state_hierarchy` to cover the cold DB migration.
