  Begin preparing DrawingAreaProxy to work with multiple web processes with site isolation
https://bugs.webkit.org/show_bug.cgi?id=250093
rdar://103881608

Reviewed by Tim Horton.

With site isolation, DrawingAreaProxy can no longer be a message sender because message
senders can only send to one process.  Instead, we use other methods to send the message.
Many of them just call m_webPageProxy.send with m_identifier, and we get the same behavior
as before in the non-site-isolated case and we can fix the necessary send calls to send
to the correct process in a coming PR.  Using m_webPageProxy.process() would be a problem
if we did anything with ProvisionalPageProxy's DrawingAreaProxy, but we currently don't.
ProvisionalPageProxy only uses it to call WebPageProxy::creationParameters which just sends
the drawing area's type and identifier to the new process.  There is potential for some
future refactoring to clean that up, but it's not too important.

Receiving messages works as it did before, except instead of registering as a message
receiver for one process and unregistering from one process in the destructor, we keep a
Vector of processes we have registered in.  This also keeps the same behavior while allowing
for development of the use of multiple processes.
