XR: Enable controller profile extensions

Enables all currently documented OpenXR controller profile
extensions (Reverb G2, Vive Cosmos, Huawei Controller) in order to
support bindings for more VR hardware.

This is necessary because, if these extensions are not enabled, the
OpenXR runtime will return an error when creating a binding with one
of these profiles.

Does not bring about any changes for users at the moment, since
default controller actions have not yet been exposed to users (will
be addressed with D10944, D10948, and D11271).
