Some users of crashpad load and unload the dll that hosts crashpad code. crashpad registers a vectored exception handler to help collect heap corruption crashes. If the dll is unloaded this handler might still be called. This CL adds a scoped handler for such registrations and uses it on Windows crashpad client. To allow this to be stored, RegisterHandler() on the client needs to move onto the client object from being a helper function.
