Session Replay: additional user analytics events for Amplitude based on feedback

[jas-kas]

Based on feedback from the team, we'd like to instrument the following user interactions:

• Click the "play" button on the Replay Details page and pause (per user)
• Which tabs in Replay Details are users clicking ("Console", "DOM Events", "Network", "Trace", "Issues", "Memory")
• Time spent on Replay Details (per user)
• Clicked into full-screen mode or exiting full-screen mode (per user)
