cursor-renderer/native: Add a means to disable HW cursors

When dealing with a faulty hardware or bugs in the driver, it might be
interesting to force the use of software cursors for debugging purposes.

Add a debug environment variable MUTTER_DEBUG_DISABLE_HW_CURSORS to
disable hardware cursors and force using software cursors.
