sf: Add basic implementation of onVsyncIdle
To adopt the new AIDL composer callback API, the patch changes the
architecture to pass HWC2::ComposerCallback directly in the
registerCallback function. The underlying implementations can use their
own bridge to adapt with different versions of callback APIs.
