Bug 2005011 - Part 3. Make gfxPlatform set the hardware codec-related gfxVars accurately on Android. r=media-playback-reviewers,padenot

This makes the gfxVars report based on the Java
HardwareCodecCapabilityUtils wrappers, so that when configure the ffmpeg
modules, we advertise the correct software/hardware support.
