python: Fix using overrides when not building PyGObject

Since 547570cd790f2b2e390edc1dfb5df4c7a33de45c we do not always build
PyGObject and our development environment is broken when trying to use
GStreamer python when built against system PyGObject with the following
error importing Gst in there:

```
12345678** (gst-plugin-scanner:710617): CRITICAL **: 11:45:02.343: can't find gi.repository.Gst

Factory Details:
```

The approach to fixing it is to implement override `gi` in
`gst-python/gi/` which we add to `PYTHONPATH`) and in there reset the
`gi` module to the right place and we get overrides from paths from
`_GI_OVERRIDES_PATH` we set in `gst-env.py` which points to all the
overrides that will be installed.

For the unit-tests, we now build one version of the test unit file per libsoup
version found. So if both libsoup2 and libsoup3 are available on the host, the

We get spurious sigint and this is just a small temporary workaround

tests: aggregator: Take `TIMEOUT_FACTOR` env var into account

This env var is set in the CI so we grow the timeout as required
(when running in valgrind for example).

Trying to avoid hitting wrong timeout in valgrind job like in:

libsoup: Bump to 2.74 to fix gssapi build failure on macOS

See: https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/255

We also need to disable sysprof by default because it only builds on
native Linux. If someone really wants it, they can enable the option
on the command-line by passing -Dlibsoup:sysprof=enabled

msdkenc: fix vp9enc initialization fail

MediaSDK does not support to handle extbuff with id
MFX_EXTBUFF_VIDEO_SIGNAL_INFO for mjpegenc and vp9enc. Hence, need to
exclude mjpeg and vp9 when passing color properties to MediaSDK during
msdkenc initialization.

tests: va: Add VA buffer copy tests.

It should only work for raw buffers, but fails on dmabuf since it
should have a drm modifier.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1023>

va: allocator: dmabuf: Use GstVaSurfaceCopy, if possible.

If dmabuf-based buffer to copy contains only one memory, and there are
memories available in the allocator's pool, it's possible a fast
memory copy using GstVaSurfaceCopy, regardless the drm modifier.

va: allocator: Use GstVaSurfaceCopy.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1023>

va: Add GstVaSurfaceCopy class.

This new class is a helper for fast/tricky copy of surfaces. First it
tries to copy using the function vaCopy in libva 1.12. If it fails, or
it's not available, a GstVaFilter is tried to be instantiated with the
allocator's parameters, and if succeed, it's used for copying the
source surface.

This is required for dmabuf surfaces with drm modifier.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1023>

va: filter: Enable to pass VASurfaceID in GstVaSample.

Initially GstVaSample processed its GstBuffer member to get the
VASurfaceID. But it might cases where we already have the VASurfaceID
to process by the filter.

This patch enables the possibility to pass the surfaces rather than
the buffers. In order to validate the surfaces a function to check
surfaces were added.
