More generic flag to prevent falling/flying entities from leaving the island

[Poslovitch]

Description

Is your feature request related to a problem?

We already have some protection about that in regards to Withers. Yet, I think the same need can also apply to a few bunch of entities that can fly over the gap between islands.

Describe the solution you'd like us to implement.

Entities such as armor stand, falling blocks, fire charges, ghasts or any other of its kind that may either damage or "grief" an island should be restricted from leaving the island space.

Describe alternatives you've considered.

None.

Additional context

None.

Have a look at GeoLimitMobsListener. Today it supports any entity that spawns, so ghasts, blazes etc. are covered:

protection:
  # Geo restrict mobs.
  # Mobs that exit the island space where they were spawned will be removed.
  geo-limit-settings:
    - GHAST
    - BAT
    - BLAZE

This request looks different because you mention armor stands, falling blocks, fire charges. Those could be added to this class maybe?

I think so.
