parse: Backport "Don't do delayed property setting..."

Backport "parse: Don't do delayed property setting for top-level
properties."

Modified version of https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/832
that only warns when trying to set a non-existent property instead of
generating a hard parse error, to preserve compatibility.
