It is not necessary to disable the thread-based drm event reading
(QT_QPA_EGLFS_KMS_NO_EVENT_READER_THREAD) anymore when using screen
cloning.

Note that this does not work when atomic commits are enabled. (i.e.
running with QT_QPA_EGLFS_KMS_ATOMIC=1 and attempting to use screens
that clone will not function as expected, regardless of which event
reading method is used - that needs a rework of how atomic requests
are handled, and is not something we are going to invest into given
that atomic is not even used by default)
Pick-to: 6.4
