Rewrite Pruning Implementation To Handle EIP 7045 (#13762)

Browse Source 
* make it very big

* use new pruning implementation

* handle pre deneb

* revert cache change

* less verbose

* gaz

* Update beacon-chain/operations/attestations/prune_expired.go

Co-authored-by: Potuz <potuz@prysmaticlabs.com>

* gofmt

* be safer
