[Feature Request] Playtime tracking

[SpunkMurphy]

Hello, other emulators like Duckstation and PCSX2 have a feature where you can see how much time you have spent playing a particular game.

It would be a great feature to add to RMG.

Currently, the only way to track amount of time playing N64 is to use Retroarch. No standalone N64 emulator has playtime tracking, yet.
