Core/SAI: Spell casts that cannot be executed because the unit is currently casting another spell will be retried asap with priority over other events (#25238)

* Core/SAI: Spell casts that cannot be executed because the unit is currently casting another spell will be retried asap with priority over other events

* Core/SAI: Re-sort the events only when needed

* Fix some priority reset and wrong mEventSortingRequired handling

* Code cleanup.
Sort only events loaded from db (not stored events, not timed action list).

* Code cleanup.
Raise priority of failed casts so they are retried before other spells

* Keep priority of the action fails and is rescheduled on next update

* Don't try recasting a spell in SMART_ACTION_CAST if there are multiple targets and at least 1 was successful
