Simple parser that only parses frame information.
This helps avoid requiring the software decoder on init to decode a
single frame, since the decoder can be quite slow.
Add a full parser to libavcodec for AV_CODEC_ID_JPEGXL. It finds the
end of the stream in order to packetize the codec, and it looks 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,
but that code will be removed and call this instead in the next commit.

Possible now that the next pointer no longer exists.

The whole old next API has been deprecated in commit
7e8eba2d87, yet deprecating the next
pointer has been forgotten (the next pointers of other structures are
below the public API delimiter, but such a delimiter doesn't exist for
AVCodecParser).

I have attempted to write a JPEG2000 Parser. Have tested
by generating a file containing 14 frames, as mentioned
by Micheal. Have also tried testing with various packet
sizes by setting -frame_size option. Additionally,
fixed a few formatting issues as pointed out by Micheal.

Simple parser to set keyframes, frame type, structure, width, height, and pixel
format, plus stream profile and level.

And add it to the CONFIGURABLE_COMPONENTS list in Makefile. This way, changes
to the new file will be tracked and the usual warning to suggest re-running
configure will be shown.
