KYRA: Rewrite the VQA decoder, using the VideoDecoder classes

There isn't really a lot of benefit to this, but I think it's nicer
if all our video decoders at least try to use the same infrastructure.
KYRA: Let the VQA decoder draw directly to the backend

As an alternative to using the Screen class's functions, we can let
the VQA decoder draw directly to the backend. This won't work if the
game uses "hi-res mode", but I don't think that's ever the case for
Malcolm's Revenge. I believe the KyraEngine_MR::playVQA() function
ensures that the screen is properly updated after the movie has
finished.

This almost limits the VQA rewrite to vqa.cpp and vqa.h. Whether it's
better this way than changing the Screen functions to take a 'pitch'
parameter...? I don't know. But it's an alternative.
KYRA: Restructure the VQA decoder, as suggested by clone2727

Untangled the audio and video track from each other, and the parsing
of the stream from the decoding of its data. Also fixed a memory leak
as it turns out deleting a Surface doesn't free its data. You have to
call free() in it.

I have only checked the intro, not every cutscene, but that seems to
work fine at least.
KYRA: Make pointers to VQAHeader const

This is just to enforce the idea that VQADecoder owns the VQAHeader
and that the audio/video tracks are only allowed to look at it, not
change it.
