graphics: add composer 2.2 default impl
This adds
android.hardware.graphics.composer@2.2-hal
android.hardware.graphics.composer@2.2-passthrough
android.hardware.graphics.composer@2.2-service
The -hal module makes it easier to write composer 2.2 HAL and is
reusable by vendors. The -passthrough module provides a HwcHal
class that implements ComposerHal 2.2 on top of hwcomposer2, and is
also resuable by vendors. Finally, the -service module provides a
(stub) default implementation.
Test: boots and VTS
