Re-implement button/slide press detection

[HelloKS]

Current implementation is using hard-coded touch collider based on Oculus quest 2 controller model. It works at least for me, but it can be feel awkward when playing this with other vr handset/controller (or just because of personal preference).

Followings are the symptoms of mismatched touch collider:

• When user tries to hold buttons for hold notes, it will missed.
• When user tries to press buttons, game will detect incorrectly (ex. Fast or Slow will appear even if user pressing it at right timing)

At current stage, I think these are solutions.

• Just use the hand model, not controller: I've tried, but it really doesn't feel right and I didn't like it.
• Make touch collider as user configurable: I think this is best way if I need to use collider, but implementation can be complex..
• Don't use touch collder, detect controller position and use it somehow: this will work too, but can't think how at this time.

Because of steamvr's implementation, I can't make fine tuned collider for Q2 controller's ring. Both controller side shares one prefab.

Edit: got report, duplicating prefab and specify R/L prefab in render model working.

Hopefully c83a218 partially fixed this issue for Quest 2. The downside of this is other HMDs controller will face more mismatch.
