handle filtered events and make it null events when there are events …

…size info

Description

backfilling parquet events processor was looping due to the failure of handling filtered events on testing txn: 1496685738
context: https://aptos-org.slack.com/archives/C03MN5F7WUV/p1721575481807169

so to avoid inconsistency, we are alined on handling in a way of inserting x "empty/null" rows for filtered events when there are x number of event size info.

Test Plan

Tested locally that it's handling all cases

1. num of events = # of events_size_info
2. num of events != # of events_size_info (events empty )
3. num of events = # of events_size_info (events_size_info empty)

Events show up in JSON but not GRPC

grpcurl -d '{ "starting_version": 1496685738, "transactions_count": 1 }' -max-msg-sz 30000000 -H "authorization:Bearer xyz" grpc.testnet.aptoslabs.com:443 aptos.indexer.v1.RawData/GetTransactions

compared to https://fullnode.testnet.aptoslabs.com/v1/transactions/by_version/1496685738

we want to be consistent about excluding and counting as excluded
