When the background had an alpha channel, the old code in blend_plane
calculated premultiplied alpha from the destination plane colors instead of the
destination alpha.

Also the calculation of the output alpha should only happen after the color
planes are already finished.

Fixes output of:
ffplay -f lavfi "testsrc2=alpha=32[a];color=black[b];[b][a]overlay[out0]"

The use of this SEI is for backward compatibility in HLG HDR systems:
older devices that cannot interpret the "arib-std-b67" transfer will
get the compatible transfer (usually bt709 or bt2020) from the VUI,
while newer devices that can interpret HDR will read the SEI and use
its value instead.

If using the winstore compat library, a fallback LoadLibrary
function does exist, that only calls LoadPackagedLibrary though
(which doesn't work for dynamically loading d3d11 DLLs).

Therefore explicitly check the targeted API family instead.

Make this check a reusable HAVE_* component which other parts
of the libraries can check when necessary as well.
