Simplify the construction of RemoteTextInputClient

Today, RemoteTextInputClient's ctor take six arguments,
all extracted manually from a ui::mojom::StartSessionDetailsPtr.

In order to simplify its construction, pass ui::mojom::StartSessionDetailsPtr
as a parameter to RemoteTextInputClient's ctor and extract
data from there.

BUG=None
