Record and display videos

Summary:
This diff adds one more section in the Support Screen V2. This section records and displays the emulator screen. Right now the videos are stored at the very same location where our currently recorded videos are stored. For displaying them on UI I have used `react-player` dependency.

For the upload bit:

I will see how the exisiting e2e tests upload videos and if we can use their approach. Or else we can just upload videos on everstore and export its handle as part of flipper trace. The last resort can be to base64 encode it along with the trace.
