Refactor WebXr with support of vr controllers

[AnthonyGlt]

Description

Refactoring of the VR. Following the work done previously and here.

Handling the controllers correctly. To do so, I've created vrHeadSet which is containing a clone of the camera (_camXR). The vrHeadSet will be used to translate the webxr scene around the globe. This is to bypass this bug which cause imprecision.
Then at each animation, I use the _camXR to update the position of our cam.
I can't directly use our default cam, because the camera needs a parent and it's position will also be affected by the position of the VR scene, which is usually set using this way:

const transform = new XRRigidTransform(offsetPosition, offsetRotation);
const teleportSpaceOffset = this.baseReferenceSpace.getOffsetReferenceSpace(transform);
this.parentRenderer.xr.setReferenceSpace(teleportSpaceOffset);

I also had to create callbacks in src/Layer/OGC3DTilesLayer.js to update the 3dtiles while being in VR.

To activate the VR, we have to pass the webXR argument in the view option. To activate the controllers, we have to pass the argument controllers to true as follows:

{ webXR: { controllers: true } }

Motivation and Context

Update the VR and get a better controllers support

##TODO

• handle xr session end
• define webxr only in globelayer
• add more functionnalities (teleportation)
• better handling of the 3dtiles update/ view update

We could see about the animation process (especially for the 3Dtiles) since you're also working on the topic for #2428
