WHY

We need support for the new TriggerArea and TriggerAreaResult components from the protocol, to be able to expose through the SDK interface the ability to use Unity's Trigger Colliders to detect OnEnter/OnStay/OnExit of scene Entities (and players) based on the SDK ColliderLayer layermask.

• ADR PR: trigger areas adr#290

WHAT

• Refactored the existent CharacterTriggerArea plugin and logic (previously used only for CameraModeArea and AvatarModifierArea components handling) into the new SDKEntityTriggerArea to:
  • Implemented support for setting the collider used as Sphere or Box (previously only Box)
  • Implemented support for setting the SDK Layermask wanted
  • Allow detecting sdk entities also, instead of just player avatars (kept the AllAvatars physics layer as an optimization to use that one on SDKEntityTriggerArea that only care for player avatars
  • The Prefab now holds both BoxCollider and SphereCollider disabled and enables the one it needs
• Implemented new TriggerAreaHandlerSystem for the new SDK component

TEST TINSTRUCTIONS

1. Download the build from this PR and use it to enter pravus.dcl.eth world
2. Approach the leftmost clickable cube and test that by clicking it you move the small cube in and out of the transparent TriggerArea -> confirm that the transparent TriggerArea color DOESN'T CHANGE
3. Then approach the rightmost clickable cube and confirm that when you click it, the monster is moved in and out of the transparent TriggerArea -> confirm that the TriggerArea color changes every time the monster enters/exits the area (sometimes it looks like it doesn't change because the randomized color ir very similar to the previous one, keep clicking to test more than once to confirm)
4. Then move the player in and out of the transparent TriggerArea and confirm that the area color also changes when entering and exiting
5. Approach the clickable SPHERE and click it to spawn a semi-transparent sphere at the top of it, that will fall with physics and disappear when it touches the clickable sphere -> confirm that the falling sphere disappears

Everything looks good. I simply have minor requests

[pravusjif]

I'll update the protocol package to point to the latest experimental package once I have the changes in that other repo merged.
