Remove ScorePerformanceCache
This class was only used in two places, both on the results screen, but
was holding references to `OsuPlayfield` game-wide (due to unrelated
issues, but still).

Because I can't really think of future use cases for this, and running
the calculation twice at results screen isn't a huge overhead, let's
just do that for now to keep things simple.
