Share the mapping from parameters to call view model options

The SDK stopped sending join notifications: it threaded callIntent into
createCallViewModel$ but not its pair sendNotificationType, which
enterRTCSession used to read for itself, so an explicit
?sendNotificationType=ring — or an intent that implies one — no longer
reached joinRTCSession.

The mechanism is worth fixing rather than the instance. The defaults on
CallViewModelOptions describe a standalone Element Call, so a widget
caller that misses a field gets standalone behaviour rather than an error,
and the SDK is only ever a widget. Give both callers one shared mapping so
they cannot drift, and cover the whole chain from URL to options in tests.

autoLeaveWhenOthersLeft and waitForCallPickup stay out of it: the view
model never read those from the parameters, so enabling them for the SDK
would be a change in its behaviour rather than a fix.
