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()`.

[more convenience setters]: #499
[it was decided]: #499 (comment 2364820)

It was useless.

We need to be able to keep a reference to the action when we
implement async action types so now we can do `action.clone()`
and get a hard reference to it.

We also need to be able to mutate the structure, it is possible to
`get_mut()` on it, get a mutable reference to the structure.

There was a bug in the test where we were using a ref to the wrong
action object in the async signal which is why we didn't detect the
problem.

Update Structure API:

* Quarks API are deprecated. Methods which were internally calling quarks
  methods now call C string based methods.
* Added new `IdStr` methods.

IdStr represents UTF-8 immutable strings which perform optimizations for short
strings (< 16 bytes). The C type `GstIdStr` was introduced in GStreamer 1.26 as
a replacement for GQuarks.

This commit adds Rust bindings for the C type `GstIdStr`. Since this type will
be used in API which previously relied on GQuarks, the commit also adds a
compatibility implementation which can be used with GStreamer versions prior to
1.26, which is the first version to implement and use `GstIdStr`.

The crate [KString] was used as the inner implementation for the compatibility
version as it performs similar optimizations as `GstIdStr` and uses the same
threshold to trigger heap allocation.

GStreamer 1.24 added `GST_OBJECT_FLAG_CONSTRUCTED`, so `ObjectFlags::all()`
returns a different set depending on the version feature.

If we really wanted to return a value, we would use `ControlFlow`. In Rust, if
we need to inform the caller that processing has stopped, we'd rather do this by
updating a variable from within the `func`.
