We need these details to initialize RemoteTextInputClient. I didn't want to pass
a StartSessionDetails here, since it contains "input_method_request" which is
irrelevant here. I didn't pass these as a struct, since creating a struct seemed
as complex as passing them in constructor. I also didn't want to introduce
setters for the ones that shouldn't change in run-time.

Since this isn't used widely, I thought this should be ok for now. If we use
this in more places, or if we need to add more details here, then we can think
of another solution.
