This commit is the AVHWAccel analogue of commit
20f972701806be20a77f808db332d9489343bb78: It moves the private fields
of AVHWAccel to a new struct FFHWAccel extending AVHWAccel
in an internal header (namely hwaccel_internal.h).

All usages of ff_hwaccel_frame_priv_alloc() have the same pattern:
Check for whether a hwaccel is in use; check whether it needs
private frame-specific data; allocate the AVBuffer and set
it.
This commit modifies ff_hwaccel_frame_priv_alloc() to perform
this task on its own.

libavcodec/hwconfig.h currently contains HWACCEL_CAP_* flags
as well as the definition of AVCodecHWConfigInternal and some
macros to create them.
The users of these two are nearly disjoint: The flags are used
by files providing AVHWAccels whereas AVCodecHWConfigInternal
is used by files providing

the only exception to this (and the reason why these checks
were added) was XvMC, but it is no more since commit

that two of the test cases are not animated, in order to help sort out

This prevents code duplication in the source form by calling the parse

Add a parser to libavcodec for AV_CODEC_ID_JPEGXL. It doesn't find the
end of the stream in order to packetize the codec, but it does look at
the headers to set preliminary information like dimensions and pixel
format.
Note that much of this code is duplicated from avformat/jpegxl_probe.c,

Before this commit, the decoder erroneously assumes that the AVFrame
passed to the receive_frame is the same one each time. Now it keeps an
internal AVFrame to write into, and copies it over when it's done.
