winebus.sys: Enable extended BT reports for DualShock 4 controllers when requested.

This happens if any of the vendor-specific reports is used.

SDL triggers the mode switch when calling SDL_GameControllerSetSensorEnabled()
on supported devices.

This is a one-way transition, i.e. cannot be undone without restarting
the controller, so it's fine to have it tied to lifetime of winebus.
