daa1519e3d nle: Add validate tests support 
This allows us to start testing internal of the elements by linking
the nle pluging directly with validate and implement validate
tests with specific action types.

a342d14ba9 ges: Add support for sources reverse playback 
It introduces a `reverse` property at the `nlesource` level which will
basically reverse playback of the clip.

We guarantee that outside that clip, the data flow looks like it was
playing forward as we add an 'identity' element with `single-segment=true`.

This start making use of the newly introduced concept of
`CHILD_PROP_FLAG_SET_ON_ALL_INSTANCES` as it is natural that
doing `source_clip.set_child_property("reverse", True)` will make
the whole clip go reverse, meaning that all the GESSource children
properties will be set. To set an individual source "reverse" child
property as the desired effect.

Fixes: https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/issues/24
Depends on: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/451

1627a944e7 nlecomposition: Use a bus message to retrieve pipeline position 
Instead of recursing up, as this will allow to have nested composition
run inside auxiliary pipelines. It is a bit cleaner also.

Subtimeline might be in an auxiliary pipeline which make the current
recurse up approach not working.

37602d1d02 ges: Keep internal stream selection messages internally 
Timeline StreamCollection are very specific to inner working of nested
timelines and should not interfere with the usual stream selection
process and are now handled as element messages.

Stream selection inside `nleobject` need to be handled internally by the
application or GES itself so we should just drop all those as they would
interfere and fail if they are exposed to other elements.

b14207cc9e nle: Use a message based mechanism to detect parent nleobject duration 
Recursing up is pretty ugly and will fail when we start using ancillary
pipelines for sources in nle, using a message/event based mechanism is
a common pattern that is much cleaner.

e3be7e3162 nlecomposition: Simplify the way we ensure stream-start is sent 
stream-start should always be sent once at the beginning of the stream,
so we should make sure it is pushed at the very beginning and after
resets (going back to READY).

7911a580c2 nle: composition: Avoid running query before being constructed 
`gst_pad_create_stream_id` runs a URI query on the element which
triggers traces for not constructed objects which fails in rust tracers
as object should have names in all traces.
