Camera2: check always for the highest supported video quality

we do not set the default quality per device on overlays. So in most cases
like it is now it would always fetch the default quality. We want always the
highest available.  So check for it. As well do not check height/width for
 the 3 main video qualities. There is no need and either the camera HAL
 support it or not. This prevendsespecially for weird camera HAL's like
 exynos4 wrong support lists

Camera2: fix array derp

we set the default quality in strings.xml to 5 but CIF is fetching in arrays.xml
the strings value. So whatever expilicit set the int values always directly in the
array.

Camera2: do not set a video quality default in video preferences

We set them now always in java code, so get rid of it here to prevend any
wrong shown starting values on first camera start.
