don't run filtered tmp processor when reingestion is enabled

[sreuland]

when a reingestion range is being run, the processor runner was still running TransactionFilteredTmpProcessor which is inserting and deleting tx's to history_transactions_filtered_tmp on every flush. This step is un-necessary during reingestion since TransactionFilteredTmpProcessor` only needs to be maintained with transactions from 'forward' ingestion to support tx sub queue processing.

In addtion, during some reingestion runs with parallel workers, observed some long running/hanging DELETE stmts left on the db server which were slowing down overall reingestion workers.

postgres=# SELECT
  pid,
  now() - pg_stat_activity.query_start AS duration,
  query,
  state
FROM pg_stat_activity
WHERE (now() - pg_stat_activity.query_start) > interval '5 minutes';
  pid   |    duration     |                                                query                                                 | state

this behavior may be related to the deadlocks situation that was noted and resolved by #5263.

This pr proposes additional changes related to reingestion sql performance on top of the deadlock fix in #5263:

• Removed EnableIngestionFiltering flag and global config variable, it is obsolete, as ingestion filter was permanently enabled, the flag provides no value.
• repoint conditional checks on running TransactionFilteredTmpProcessor to reference ReingestionEnabled instead of EnableIngestionFiltering, this allows the parallel reingestion workers to skip doing that, thus avoiding that additional sql activity

Closes #5277
