camera: vndk: migrate from NativeHandle to ANativeWindow

The client side implementation of Camera vNDK used
NativeHandle to parcel NDK ANativeWindow, because ANativeWindow
wasn't parcelable over stable interfaces until recently. However,
this introduced an implicit dependency on HIDL as encoding
ANativeWindow to NativeHandle required HIDL Token Manager.
HIDL Token Manager is deprecated and scheduled to be removed soon.

This CL updates the client side vNDK implementation to use
ANativeWindow instead of NativeHandle. This includes updating
the shared code, which had special handling for when built for
the vNDK.
