feat: support native MacOS screen capturer

[VerteDinde]

Description of Change

This PR adds support for MacOS 15 Sequoia's native system picker as part of the desktopCapturer API. The API now includes an isDisplayMediaSystemPickerAvailable check and an option to getNativePickerSource, which returns the selected native picker media stream.

This API does not allow a user to differentiate between screens and windows, following similar MacOS API implementations - we can add that differentiation to the API.

Currently in draft to take API comments/considerations.
