Fixing warnings

assertion 'start < end' failed
Although when QSV runtime reports a codec is supported, resolution query
fails sometimes, espeically VP9 encoder case on Windows.
Don't try to register an element if resolution query returned an error

A fence configured in GstD3D12Memory should be used only for
write access to be completed. And because d3d12 -> d3d11 copy path
is read access to d3d12 resource, we should not set fence to
memory. Otherwise another read access to the d3d12 resource
will wait for d3d11 device context's copy operation although
simultaneous read access is allowed.
Use background thread to keep d3d12 resource and wait for d3d11 device's
copy operation instead.

Doing so resets the stride from the VideoMeta and it wasn't done before
the commit below. While on it, drop the plane size check as we can't
reliably predict the correct size when using DRM modifiers.

null event NT handle to ID3D12Fence::SetEventOnCompletion()
will block the calling CPU thread already, thus it has no point that
creating an event NT handle in order to immediate wait for fence at CPU-side.
Note that passing a valid event NT handle to the fence API might be useful
when we need to wait for the fence value later (or timeout is required),
or want to wait for multiple fences at once via WaitForMultipleObjects().
But it's not a considered use case for now.

GstD3D12Window.priv.input_info is referenced by mouse event handler
in order to calculate corresponding original position

The driver - AKA intel-vaapi-driver - has been unmaintained for four years
now and encoding appears to be broken in various cases. As it's unlikely
that the situation will improve, blocklist the driver for encoding.
Decoding appears to be stable enough to keep it enabled.
The driver can still be used by setting the `GST_VA_ALL_DRIVERS` env
variable.

The driver frame counters (processed, dropped, buffer level) are not
always correct apparently, and don't allow reliably assigning a frame
number to captured frames.
Instead of relying on them, count the number of frames directly here and
detect dropped frames based on the capture times of the frames: if more
than 1.75 frame durations are between two frames, then there must've
been a dropped frame.

If a d3d12 memory holds non-direct-queue fence but the fence was
created with D3D12_FENCE_FLAG_SHARED flag, use the fence instead of
waiting for fence at CPU side. Note that d3d12ipcsrc or
d3d12screencapture elements will hold such sharable fence.

When building for iOS in Cerbero, as of MoltenVK SDK 1.3.283, we have
to statically link to libMoltenVK since it no longer ships a dylib.
This requires linking to libc++, so we find the dep with the objc++
compiler to ensure that meson uses the right linker.

The code is simplified by using GQuarks for looking for caps features, and
removing inner loops.
Also, it's used the pad template caps to compare with the incoming caps because
is cheaper at the beginning of negotiation, where the pad template caps is used.
And, since the ANY caps where removed, there's no need to check for an initial
intersection.
Finally, the completion of caps features is done through a loop.

The ANY caps in pad template caps seems to mess up the DMA negotiation.
The command of:
GST_GL_API=opengl gst-launch-1.0 -vf videotestsrc ! video/x-raw,format=NV12 !
vapostproc ! "video/x-raw(memory:DMABuf)" ! glimagesink
fails to negotiate, but in fact, the vapostproc can convert the input NV12
formant into the RGBA format to render.
The ANY may help the passthough mode, but we should make the negotiate correct
first.

After signal recovery the capture times for the next frames are simply
wrong. Experimentally this affected 2-3 frames and seemed to be related
to the buffer fill level after signal recovery, so drop at least 5
frames and up to fill level + 1 frames in this situation.

Since a buffer resource will occupy at least 64KB,
allocating upload resource per decoding command might not be
an optimal approach. Instead, use sub-region of a upload resource
for multiple decoding command if sub-regions are not overlapped
each other.

When enable parallel encoding, it is possible that the unshown frame
is not output but it is already be marked as a repeated frame header.
So we need to use a dedicated buffer to hold the repeat frame header,
don't mix it with the orignal frame data.
