turnip: expose support for VK_EXT_acquire_drm_display
Turnip supports VK_EXT_direct_mode_display
and can use the common
implementation of AcquireDrmDisplayEXT()
& GetDrmDisplayEXT()
(which use
wsi->can_present_on_device()
that turnip implements).
Untested because I don't have the hardware (and the CTS doesn't have tests for this).
