Problem
Once the accounts delta hash is removed (#4441), we no longer need the background account hasher.
Summary of Changes
Conditionally start the background hasher based on if the feature is enabled or not.
Justification to Backport
This PR is related to the feature gate for removing the accounts delta hash (#4441), which is in v2.2. When the feature gate is enabled, we need to stop sending accounts to the background thread to be hashed. More context here: #4842 (comment)
