a0821345eb avformat/mov: Add support for demuxing still HEIC images 
They are similar to AVIF images (both use the HEIF container).
The only additional work needed is to parse the hvcC box and put
it in the extradata.

With this patch applied, ffmpeg (when built with an HEVC decoder)
is able to decode the files in
https://github.com/nokiatech/heif/tree/gh-pages/content/images

Also add a couple of fate tests with samples from
https://github.com/nokiatech/heif_conformance/tree/master/conformance_files

Partially fixes trac ticket #6521.

440e08e4bb configure: autodetect libdrm 
option kernel_driver for vaapi device creation can be used to choose the
desired device on Linux, which is more convenient than DRM render node
in a multiple-device system (e.g. Intel iGPU + AMD dGPU or inverse), but
this option requires libdrm works. vaapi is autodetected at
configuration time, let's make libdrm autodetected too.
