[Bug Fix] Dire Charm Reset (#3875)

* [Bug Fix] Dire Charm Reset

Added Druid and Necro Dire Charm to Failure Check

* [Rule] RequireMnemonicRetention for Spells 9-12 Rule

Rule is default false to maintain current server setup.

Enabling will require clients to have the required ranks of Mnemonic Retention in order to cast.

This is a stopgap as on live, the buttons are not even available to use. This will mimic the functionality but denying the cast.

* Revert "[Rule] RequireMnemonicRetention for Spells 9-12 Rule"

This reverts commit c65e86223d.
