gst: deprecate maybe_field() setters in favor of field_if_some()

Browse source 
Some builder convenience setters where added to work with `Option`al values.
This is the case for the `Pad` builder setter `maybe_name()` which was
introduced as part of [this MR].

Then [more convenience setters] were discussed and [it was decided] to use
`field_if_some()` instead of `maybe_field()`. Existing `maybe_field()`s were
kept for backward compatibility. This commit marks them as deprecated,
referring to the matching `field_if_some()`.

[this MR]: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/-/merge_requests/1255
[more convenience setters]: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/-/issues/499
[it was decided]: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/-/issues/499#note_2364820
