frameworks/base: Add support for low resolution rendering

This change is a combination of following changes:

1) frameworks/base: Handle custom activityTrigger flags
    * Take necessary action needed for each vendor specific flag
    set as part of activityTrigger.
    * If the HW acceleration has to be enabled for a particular
    activity, populate the neccessary activityInfo flags.
    * If the resolution needs to be overridden for SurfaceView
    of a specific app, set the overrideRes to 1 in applicationInfo.

2) frameworks/base: Add support to render certain apps at lower
                    resolution.
    Add support to render certain apps at a resolution lower than the
    primary display device resolution. This would reduce the load on
    GPU and would help in saving power

This change also moves out custom functionality related to
overriding resolution from SurfaceView, to a new class
ResolutionOverride.
