[ParticleEmitter3D] Performance tanks over time after many emitters are created and then deleted

3D particle emitter 3.1.0

Describe the bug of the extension

When creating a 0.1 duration particle effect every frame at a location*, set to automatically delete, the game's performance slowly gets bogged down to the point of not being able to maintain a steady frame rate. I tested manually deleting the emitters after a 0.1 wait instead of letting them delete automatically and the problem persisted. When using the same event setup to instead spawn and then delete a 3D Model no performance issues were observed.

(*I'm aware this likely isn't a very efficient way or the intended way of using this plugin, it was a temporary setup for what I was testing)

I confirmed in the debugger that the instances are being deleted, however the performance hit can be seen observed in the Profiler.

Steps to reproduce

1. create an emitter at a location every frame and then have it automatically delete itself or delete it with an event
2. wait for a couple of minutes and observe the performance

I just found this issue on the main Gdevelop repo: 4ian/GDevelop#6003

Apologies that I didn't see it earlier since it didn't appear when I searched here.

It describes the same issue I'm having with the 3.1.0 version of the extension.
