[Pico] Workaround input profile selection in Pico4 Ultra

The OpenXR runtime in the Pico4 Ultra incorrectly selects the
Khronos simple profile instead of the more specific Pico4 one
provided by the XR_BD_controller_interaction extension.

This results in Wolvic rendering a generic trigger controller
instead of the actual 3D model for Pico4 Ultra controllers.
