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
