support app sharing in screen capture

[creativecbr]

Hello everyone, my issue revolves around the inability to share app content during screen sharing. I attempted to use MacOSScreenCapturer.sources with the parameter includeCurrentApplication set to true, but unfortunately, it did not yield the desired outcome.

In order to address this issue, I made the following pull request (PR) changes. In these changes, I introduced the includeCurrentApplication parameter to ScreenShareCaptureOptions and utilized it to exclude the app filter in MacOSScreenCapturer. This modification enables the retrieval of sources as demonstrated in the following code snippet:

_ = MacOSScreenCapturer.mainDisplaySource().then { displaySource in
    Task {
        let options = ScreenShareCaptureOptions(dimensions: .h720_43,
                                                fps: 5,
                                                includeCurrentApplication: true)

        let mainTrack = LocalVideoTrack.createMacOSScreenShareTrack(source: displaySource, options: options)

        Task { @MainActor in
            self.tracks = [mainTrack]
        }

        await withThrowingTaskGroup(of: Void.self) { group in
            group.addTask {
                try await mainTrack.start()
            }
        }
    }
}

This solution consistently works and provides a convenient resolution. If there is a misunderstanding on my part, and the issue can be resolved without these changes, please reach out to me and provide an explanation.

Thank you in advance!

I can't sign CLA. Although I have added an email address to my GitHub account, I suspect that the error may have occurred because I pushed a commit without configuring the git user.email. How can I rectify this situation?
