There are different ways to iterate over an SkPath or an impeller::Path
and various points in the engine source tree we have boilerplate
duplicates of this code to transfer the contents of the DlPath wrapper
object into some platform-specific path. This PR adds a
dispatch/receiver mechanism to read back the contents of a DlPath -
independent of whether it is backed by an SkPath or an impeller::Path -
in a simpler form that avoids potential mistakes in the various
conversion methods.
See DlPathReceiver and DlPath::Dispatch in the dl_path.h file
