SF: Remove display config functions from HWC2
HWC2 is unnecessary stateful stopgap between HWComposer and
ComposerHal. In this CL the following functions are removed from HWC2
* getActiveConfig
* getActiveConfigIndex
* getDisplayVsyncPeriod
and ComposerHal is called directly from HWComposer. This way display
configs are stored only in HWComposer.
Additionally HWC2::Display::Config is renamed to DisplayMode and
it's extracted in its own file.
From the perspective of SurfaceFlinger this CL is not modifying
behaviour.
