hwc: Add support for panel resolution switch
Add support for panel resolution switch. This feature makes use of
the Linux modedb feature that lists available modes in
/sys/class/graphics/fb0/modes and accepts a mode change when written
to /sys/class/graphics/fb0/mode
Clients can link to APIs exposed in display_config.h, these
internally resolve to binder calls into HWC. For debugging, mode
changes can be made over binder using shell commands.
adb shell service call display.qservice CODE ARGS
ARGS can include config index and display (only primary supported)
