Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/4317
This patch fixes a regression in
a35bf1e3847351703542869755b6b9e536b9d2fd.
The new calls to tracers in the affected change were being done while
holding the pad object lock, which wasn't the case in the old ones,
leading to the latency tracer deadlocking in gst_object_get_parent().
The dependency on the pad lock for those calls was accidental. This
patch removes it by temporarily unlocking during the affected calls,
not unlike how it's done when calling a probe callback or the
send_event() function of the downstream element.

When GST_DISABLE_GST_DEBUG is defined, the log context functions were
missing their stub implementations, causing link errors. Add the missing
stub functions to the disabled debug section.
Also add (nullable) annotation to gst_log_context_get_category since
it can return NULL when debugging is disabled.

Add a new API to control logging behavior, particularly for implementing
"log once" functionality and periodic logging. This helps avoid spamming
logs with repetitive messages.
The API provides:
- Static and dynamic context creation
- Configurable message identity calculation
- Periodic reset capability
- Context-aware logging macros
- Element message variants with context support

By design, unixfd is meant to be used for zero-copy and failing when the data is
not FD based memory is wanted to help debug pipelines. Though, there exists
cases, notably with RTP payloader and demuxers, where its not possible
to get all the data into FD memory through allocation queries.
To allow using unixfd for these cases, introduce a property on the unixfdsink
that enable copying the non FD data into freshly allocated memfd.

Similar to NV12_10LE40, this is a 422 variant. This format is also named
NV20 (20bit per pixels) in other stack and is produced by rkvdec
decoder.

Calculating intersection-of-union (IoU) is a very common operation used by
tensor-decoder handling tensors from vision models. Having this in a library
will improve maintainability and ease of writing tensor-decoder.
- Post-fix _uint: We might eventually want to handle different datatype that we
woule post-fix with _type

If the vulkan plugin was compiled against a newer version than the supported
vulkan runtime instance or device, then it was possible for format retrieval to
fail. Failure was due to unconditionally using newer extensions and features
without runtime checking them.

Scenario is using wayland with this pipeline: videotestsrc ! glupload ! qml6glsink.
First pipeline and qml construction works just fine. However if all GStreamer
and QML scenegraph resources are removed, GStreamer will call eglTerminate() and
sever the connection to the display server for Qt. When Qt attempts to do any
further GL operations like construct a new QML scene, it can crash in any number
of places as libEGL will start returning NULL or other unexpected values.
What we really need is to ensure that if an external API (e.g. Qt) will
eventually call eglTerminate(), there is no need for GStreamer to call
eglTerminate(). This is what the foreign display flags allows setting.
There is also another possible scenario where one may like to make GStreamer
assume ownership of an EGLDisplay and thus eventually call `eglTerminate()`. As
such, it is now also possible to mark an GstGLDisplayEGL as non-foreign.
