The OMX stack of the zynqultrascaleplus (the only one supporting
NV12_10LE32 and NV16_10LE32) will now pick the proper profile if none
has been requested. Best to rely on its default than hardcoding a
specific one in gst-omx.

0xffffffff is the magic number in gst-omx meaning 'the default value
defined in OMX'. This works fine with OMX parameters which are only set
once when starting the component but not with configs which can be
changed while PLAYING.
Save the actual OMX default bitrate so we can restore it later if user
sets back 0xffffffff on the property.
Added GST_OMX_PROP_OMX_DEFAULT so we stop hardcoding magic numbers
everywhere.

We weren't using the usual pattern when re-setting the bitrate:
- get parameters from OMX
- update only the fields different from 0xffffffff (OMX defaults)
- set parameters
Also added a comment explaining why we re-set this param.

- Report the error from OMX if any (OMX_EventError)
- If not report the failing to the application (GST_ELEMENT_ERROR)
- return GST_FLOW_ERROR rather than FALSE
- don't leak @frame

We already have the exact same message at the beginning of
gst_omx_video_enc_handle_frame(). Having it twice is confusing when
reading/grepping logs.
I kept the earlier one to keep the symetry with
gst_omx_video_dec_handle_frame().

Check input buffers for ROI meta and pass them to the encoder by using
zynqultrascaleplus's custom OMX extension. Also add a new
"default-roi-quality" in order to tell the encoder what quality level
should be applied to ROI by default.

The 'target-bitrate' property can be changed while PLAYING
(GST_PARAM_MUTABLE_PLAYING). Make it thread-safe to prevent concurrent
accesses between the application and streaming thread.

I spent quiet some time figuring out why performance of my pipeline were
terrible. Turned out it was because of output frames being copied
because of stride/offset mismatch.
Add a PERFORMANCE DEBUG message to make it easier to spot and debug from logs.

WARNING: Trying to compare values of different types (str, int).
The result of this is undefined and will become a hard error
in a future Meson release.
Also remove unused libversion/soversion.
The OMX specs defines 8 headers that implementations can use to define
their custom extensions. We were checking and including 3 and ignoring
the other ones.

We are now always checking which files are present or not, even when using our
internal copy of OMX, rather than hardcoding the ones present in it.

It seems cleaner to use the proper meson tools to include this path
rather than manually tweak the build flags.
This also allows us to simplify the OMX extensions detection code. We
are now always checking which files are present, even when using our
internal copy of OMX, rather than hardcoding the ones present in it.
