The current encoder will hang when EOS comes. When we call the
gst_vaapi_encoder_encode_and_queue(), we should release the stream
lock, just like what we do in gst_vaapiencode_handle_frame().
The deadlock happens when: The input thread holding the stream lock
is using gst_vaapi_encoder_create_coded_buffer() to acquire a coded
buffer, while the output thread which holding the coded buffer resource
is acquiring the stream lock in _push_frame() to push the data to
down stream element.

If the pad is already fixed the caps query have to be reply with the
current fixed caps. Otherwise the query has to be replied with the
autogeneratd src caps.
This path fix this by falling back to the normal caps query processing
if the pad is already fixed. Otherwise it will fetch the allowed src
pad caps.

Since commit 9f627ef2 if the user sets level in the encoder src caps
the caps negotiation is rejected.
But since the same commit the same encoder set the autoconfigured
level in caps. Some change in the base class might fixed the operation
order so now the caps are set and later negotiated.
This patch removes the level check.

Since nobody uses it, just remove it.
Thus extract_allowed_surface_formats() is refactored to attend only
gst_vaapi_plugin_base_get_allowed_sinkpad_raw_caps().
Now a surface is created when the image chorma is different from the
previous one. And if the driver has the quirk, it outputs all the
supported image formats without trying them.

The try-and-error approach for getting the possible image formats from
a surface has brought several problems in different drivers, from
crashes to drop in performance.
Instead of that we change the algorithm to determine the possible
image formats based in the surface chroma: only those available image
formats with same chroma are exposed as possible raw caps.
Do this is important to avoid performance degrading in raw sinks
which doesn't handle NV12 but it does YV12 or I420.

Implements new vmethod gst_vaapi_window_set_render_rectangle,
which is doing set the information of the rendered rectangle set by
user.
This is necessary on wayland at least to get exact information of
external surface.
And vaapisink calls this when gst_video_overlay_set_render_rectangle is
called.

In h265, bigger profile idc may not be compatible with the small profile
idc. And more important, there are multi profiles with the same profile
idc. Such as main-422-10, main-444 and main-444-10, they all have profile
idc 4.
So recording the max profile idc is not enough, the encoder needs to know
all allowed profiles when deciding the real profile.

Instead of generating allowed srcpad caps with generic information,
now it takes the size an formats limits from the decoder's context.
This is possible since srcpad caps are generated after the internal
decoder is created.
The patch replaces gst_vaapi_decoder_get_surface_formats() with
gst_vaapi_decoder_get_suface_attributes().
From these attributes, formats are only used for VASurface memory
caps feature. For system memory caps feature, the old
gst_vaapi_plugin_get_allowed_srcpad_caps() is still used, since
i965 jpeg decoder cannot deliver mappable format for gstreamer.
And for the other caps features (dmabuf and texture upload) the
same static list are used.
This patch also adds DMABuf caps feature only if the context
supports that memory type. Nonetheless, we keep the pre-defined
formats since they are the subset of common derive formats formats
supported either by amd/gallium and both intel drivers, since,
when exporting the fd through vaAcquireBufferHandle()/
vaReleaseBufferHandle(), the formats of the derivable image cannot
be retriebable from the driver. Later we'll use the attribute
formats for the DMABuf feature too, when the code be ported to
vaExportSurfaceHandle().
Finally, the allowed srcpad caps are removed if the internal decoder
is destroyed, since context attribues will change.

Since negotiation depends on caps order, first is VA, then DMABuf,
later GLUploadTexture (deprecated) and finally raw.
Also, for decoders, the possible available color formats for DMABuf
is extended to all the possible VA color formats.

Like build_template_raw_caps_by_codec(), this function can detect and
build the caps for specified codec based on the query of the profiles.
The result is coded caps such as video/x-h265, video/x-h264. The result
can be used as the template of encode's src or decode's sink.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer-vaapi/-/merge_requests/354>
The synthetic profiles, such as H264 baseline, H265 intra, etc. are
added at the end of processing all available VA profiles. This
generated an non-optimal caps for negotiation, since the synthetic
profiles don't have frame size ranges.
This patch adds those possible synthetic profiles when the associated
profile is processed, with its frame size ranges.
Now allowed sink caps are simpler.

Instead of using dmabuf allocator in source pad, when raw video caps
are negotiated, it uses VA allocator as before, since it is stable
in more use cases, for example transcoding, and more backend drivers.
Dmabuf allocator is only used when dmabuf caps feature is negotiated.
