706ed34ce7 ffmpeg: Don't require a known device to pass a frames context to an encoder
The previous code here did not handle passing a frames context when
ffmpeg itself did not know about the device it came from (for example,
because it was created by device derivation inside a filter graph), which
would break encoders requiring that input.  Fix that by checking for HW
frames and device context methods independently, and prefer to use a
frames context method if possible.  At the same time, revert the encoding
additions to the device matching function because the additional
complexity was not relevant to decoding.

Also fixes #8637, which is the same case but with the device creation
hidden in the ad-hoc libmfx setup code.

8abd3b2028 ffmpeg: Use hardware config metadata with encoders
This can support encoders which want frames and/or device contexts.  For
the device case, it currently picks the first initialised device of the
desired type to give to the encoder - a new option would be needed if it
were necessary to choose between multiple devices of the same type.

a444863738 ffmpeg_hw: Treat empty device string as no device setting
The implementation will use some default in this case.  The empty string
is not a meaningful device for any existing hardware type, and indeed
OpenCL treats it identically to no device already to work around the lack
of this setting on the command line.

b0cd14fb1d ffmpeg: Use codec hardware config to configure hwaccels
Removes specific support for all hwaccels supported by the generic code
(DXVA2, D3D11VA, NVDEC, VAAPI and VDPAU).
