[ENGINE] Implement queue system for actions

[SchauweM]

Game Engine Feature Description

As a plugin developer, I expect to be able to assign priority to action hooks that can place them into an action queue to be executed asynchronously.

Many actions in-game are queued by priority, these queues are applied to all actors (both players and npcs).

There are three priorities that can be assigned to actions:

Weak

Weak actions cancel whenever any other action is performed - movement, opening an interface, other weak actions, etc. Weak actions are ignored if a normal or strong action is running.

Normal

Normal strength actions will pause and wait for opened interfaces to be closed before continuing to execute. Normal actions are cancelled by movement, other normal strength actions, and strong actions.

Strong

Strong actions will close opened interfaces in order to execute. Strong actions can only be cancelled manually or via expiring/executing naturally.

Acceptance Criteria

TBD - Needs Workshopping

Additional Information

We need to figure out what action does what and implement accordingly. A good action priority queue implementation is present in https://github.com/rsmod/rsmod
