Description:

When used with a headset capable of AR, the ar-hit-test component currently projects its ray from the headset, which is suboptimal UX when tracked controllers are available.

Changes proposed:

This change adds a new HitTest component, using the first tracked controller's targetRaySpace.

hit-testing has only been tested with a Quest 1 headset

Also fixes bug #5315

I can confirm that this fixes https://github.com/aframevr/aframe/issues/5315 for me on multiple Android phones.
