[calls] Introduce CallsUiCallData to feed CuiDisplay

[Evangelos Ribeiro Tzaras <devrtz src gnome org>]

commit 4321381f23c198c09c03bdb99e700ae800b7c8cd
Author: Evangelos Ribeiro Tzaras <devrtz fortysixandtwo eu>
Date:   Fri Oct 1 18:35:00 2021 +0200

    Introduce CallsUiCallData to feed CuiDisplay
    
    We need a proxy object because implementing the CuiCall interface in the
    CallsCall base class has it's own set of problems (f.e. the "state" property
    would have a type collision CallsCallState vs CuiCallState).
