Add screen mirroring in Infotainment.vspec
This PR is rework of PR #699 . The type of SmartphoneScreenMirroring.Resolution is changed to 'sensor'.
The differences of smartphone screen mirroring with smartphone projection as follow: Screen Mirroring, such as through AirPlay, mirrors all activities of a device’s screen, allowing every detail to be displayed on a secondary screen. On the other hand, existing Projection specifically targets in-vehicle use, selectively providing access to certain applications in smartphone like navigation and music players. Specifically, Screen Mirroring enables the casting of applications not typically offered by Projection, such as 'YouTube', to a vehicle's display. Therefore, Screen Mirroring and Projection are parallel technologies, each serving distinct use cases without overlapping functionalities.

I resolved the DCO error before the meeting. Thanks for your summary.

Trying to summarize my view on this PR.
- At last meeting we agreed to use
WIFI
rather thanWI-FI
to avoid changing name of other already existing signals usingWIFI
- For the other signal, maybe we should clarify that the signal concerns currently used resolution to avoid ambiguity
At next meeting I suggest that we agree on remaining needed changes (if any) , so that we can merge it as soon as they have been fixed

Thanks for your clarification.
In my personal opinion, resolving the ambiguity surrounding 'resolution' is challenging in our current signal. This is because, we don't have a specific signal for display-related and resolutions with in our spec.
I think for this issue, we need to discuss adding the display-related signal before. Once this is added, we can clarify what 'resolution' means in the context of screen mirroring.
Therefore, my suggestion for this PR is removing the resolution signal for this time. And I will prepare another PR for the display related signal for the infotainment system.
Thanks.
MoM:
- OK to merge if resolution signal removed
- Richard Fernandes - Resolution can be complex due to DRM, we from AOSP could possibly contribute

Thanks for your feedback and the decision. I just removed the resolution in my PR.
