In the CI we don't have x11 or wayland compositor running,
so the va plugins don't initialize and the tests will keep
running against software encoders/decoders.
However when running locally or inside toolbox, this will
allow va plugins to initialize and be tested.

This commit adds a Find Module implementing the necessary logic to link
against GStreamer, while implementing some extra bits to enhance the
compatibility.
The first addition is the `mobile` target, which implements the
monolithic `gstreamer_android` library, and which here gains
compatibility with Apple's operating systems.
The second addition is the handling of the basic GStreamer libraries as
`--whole-archive` when statically linked, which was ported from the
ndk-build project in Cerbero. This is not easy to do, as CMake suffers
from several issues that impede its proper usage of pkg-config:
- It cannot differentiate between system/compiler specific libraries
e.g. `-lm`, `-ldl`, but especially `-framework Cocoa`.
- It does not support `--whole-archive` natively until 3.27
- It attempts to reorder flags blindly by separating them with spaces,
thus requiring the use of `-Wl,` wrapping or (in the case of Apple
frameworks) manual framework lookup
The third addition is the port of the Fontconfig and ca-certificates
bundling logic.

The calculated position was off. I'm not sure of the exact cause;
possibly because we're in AU-aligned byte-stream mode, which means
`transform` is true.
Replacing the math that calculates the NALU positions with code more
similar to what is already in use for `idr_pos` seems to have fixed it.

We do not own any ref to queries when running them.
If we end up processing the query from the streaming thread, it means that it was
a serialized query, and the query is being waited to be processed on the sinkpad
streaming thread, thread which owns the reference.

Use a path, which contains the namespace and the repo name instead of
the complete URL when triggering the Cerbero CI pipeline. Some of the
jobs in the Cerbero pipeline (specifically the examples build) need to
curl the API, and they need the path for that, not the website or git
URL.

Add missing pixel format constants, and mappings for
P010, packed variants of 420 and RGBA layouts to GStreamer
buffer formats. This fixes problems with android decoders
refusing to output raw video frames with decoders that
announce support for these common pixel formats and
only allowing the 'hardware surfaces output' path.

Previously the wrapping of the 24-bit reference time was not handled
correctly when transforming it into GstClockTime. Given the unit of 64ms
the span that could be represented by 24 bits is 12 days and depending
on the start value we could get a wrapping problem anytime within this
time frame. This turned out to be particularly problematic for the GCC
algorithm in gst-plugins-rs which tried to evict old packages based on
the "oldest" timestamp, which due to wrapping problems could be in the
future. Thus, the container managing the packets could grow without
limits for a long time thereby creating both CPU and memory problems.

Don't assume that video/x-raw caps means buffers are mappable
or can be processed by videoconvert and friends. Only plug
those converters for real system memory, and treat other
memory capsfeatures as hardware surfaces

Some file format standards don't require mastering-display-info
and content-light-level values to be provided.
Decklink however requires the static HDR metdata for the PQ transfer
function which we may not have.
CTA-861-G mentions that in this case, 0 may provided as an 'unknown'
value which is what we use here.
