Internal Bevy XR Crates

[mrchantey]

Now that RenderTarget::TextureView has been merged we may start to see external XR crates appearing. It might be worth getting ahead of crate organization sooner rather than later.

Current Status

• bevy_xr reserved by bevy
• bevy_openxr currently owned by @blaind
• bevy_webxr currently available
• bevy_vision_os currently available

It may be possible to cram the implementations into bevy_xr but to me that sounds messy. I'm guessing bevy_xr would contain the common traits etc, and the others would contain implementations and device specific features. If we intend to have internal XR implementation crates should we start transferring and reserving the ones we'd need?

Either way, I think it may be worth it to add those available ones to https://github.com/bevyengine/bevy-crate-reservations
