Camera2: Preview needs to be stopped when changing resolution

This was done in startPreview as a hack, but was removed in
f729b85e12cfa2674048d8cce2f724014b8fc910. Specifically add it
back when the resolution is changed.

Change-Id: I306abd788bafdff4e6fba7eec4e6ff05bb3cc47c
add support to high and low video quality

although its already declared in arrays but unused
it will enable legacy devices for video recoding min/max
supported resolutions

all resolutions setup should be defined in media_profiles.xml

also, add missed resolutions for legacy devices
