Add SupportsAllAllowedBy() function to ReceiverSession inner classes

This CL does the following:
- Add copy ctors for ReceiverSession inner classes. This is required
  so that a Preferences object may be copied to a unique_ptr for
  initialization of the `cast_streaming` component in Chromium, while
  also maintaining a local instance for use with the below function.
- Add SupportsAllAllowedBy() functions for comparing the support
  provided by two different Preferences instances. This is required
  because the Cast Web Runtime allows for updating of supported AV
  settings during runtime, so it must be validated that the
  configuration used for negotiation is no more strict than that
  supported at any time by the runtime.
