Av3Emulator rollbacks customized avatar colliders to colliders from avatar

[anatawa12]

With debug inspector, we can customize bones for finger coliders and that can be used to touch something with non-finger bones (with losing one finger bone for touch).

However, Av3Emulator cannot emulate this because Av3Emulator calls AvatarDescriptorEditor3.UpdateAutoColliders, which overrides transform for finger colliders with actual (humanoid) finger colliders.

In 3.4.7, I have disabled forcing UpdateAutoColliders by default, and made it an optional setting ForceUpdateDescriptorColliders that can be toggled on in settings.

This should achieve better compatibility by default, since the colliders are only updated by the Avatar Descriptor editor inspector.
