Add qt_internal_undefine_global_definition function

qt_internal_undefine_global_definition disables an internal global
definition that is defined by the qt_internal_add_global_definition
function for a specific target.

Remove the ability to set the custom "undefine" flag for the
definitions since it's hard to control it using the introduced
function.
