cursor-renderer-native: fallback to texture cursor

Browse Source 
In some cases the hardware cursor is invisible when Mutter is launched from the
TTY, due to drmModeSetCursor2 failing without a fallback being set.

This patch captures the return value of drmModeSetCursor2 and in case of an
error, enables the texture based fallback. It adds a `broken` state, that is
checked in should_have_hw_cursor() and
meta_cursor_renderer_native_realize_cursor_from_*() to avoid copying every
cursor into a gbm buffer when we know it will fail every single time.
