Subject: Convert DynamicDisplayInfo to AIDL parcelable

And migrate related ISurfaceComposer::getDynamicDisplayInfo() method to AIDL.
(1) add android::gui::DynamicDisplayInfo etc. for serialization
(2) remove serialization code from the orignal DynamicDisplayInfo and
DisplayMode and HdrCapabilities classes
(3) convert between ui::DynamicDisplayInfo and gui::DynamicDisplayInfo

Bug: 220074970
Test: manual
Change-Id: If3c81c5fd006c281f6d38766bf415a971b0a1925
