Add optional event implemented and event detect kwords to attribute and AttrData classes

Closes #548 (closed)

I added optional kwords

alarm_event_implemented = False
alarm_event_detect = False
archive_event_implemented = False
archive_event_detect = False
change_event_implemented = False
change_event_detect = False
data_ready_event_implemented = False

to the attribute and AttrData classes, so now we can inform tango core, that events are emitted by code at the time we create attributes. E.g.

    @attribute(
        alarm_event_implemented=True,
        archive_event_implemented=True,
        change_event_implemented=True,
        data_ready_event_implemented=True,
    )
    def attr_decorator_with_kwords(self) -> int:
        return 0

    attr_class_with_kwords = attribute(
        alarm_event_implemented=True,
        archive_event_implemented=True,
        change_event_implemented=True,
        data_ready_event_implemented=True,
    )

    def read_attr_class_with_kwords(self) -> int:
        return 0
