Add minimal playtime tracking frontend

Continues work from #4108

Feel free to change things around. My goal was to just make a minimal UI to surface these values and lay the groundwork for future enhancements.

This is exactly how I imagined it!

Is there any performance penalty using this feature? I mean, for example, how often does it save the values to DB on disk? Could it affect e.g. a game that reads a lot of data from disk?

I mean, its something extra running, so it will consume resources. That being said, the impact is negligible, I would say:

• Additional CPU usage: << 0.1% of a single core
• Additional memory: < 10 KB (one session) up to a few hundred KB with many concurrent games running
• Additional disk writes: A handful of small writes per session start/finish plus one write per heartbeat (default to 60 seconds); well below background noise compared to game asset streaming
• Long-term disk space: Likely under a few MB after many years of use for typical play patterns

SQLite is one of the most optimized pieces of software out there, its designed for resource-constrained environments. So long story short: dont worry about it.

Would it make sense to change the "last played" and "playtime" to "last ran" and "runtime"? I mean, Bottles can be used to run games and programs. Played and playtime feels weird for a program. Ran and runtime are more neutral and work for both programs and games.

Open an issue asking about it, I'm sure the maintainers will take it in consideration. This PR is already merged and I will probably work on some other projects for a while before incrementing this feat.
