ProcessController should handle displaying tray icon graphic for high core counts > 16

[cb88]

If the vertical lines don't fit > 16 threads perhaps a heatmap could be used instead for higher core counts or a second icon or wider Deskbar tray item could be displayed (not sure this is possible).

Hitting this issue where the tray icon looks corrupted on an 8core/16thread Ryzen 1700x which is practically mainstream these days! A ThreadRipper 2990WX might cause it to burst into flames!

This probably needs to be tested to at least 128 cores to be slightly future proof (I think you can fake cores in QEMU?). AMD's TR 2990WX if Haiku could boot on it already has 64 threads. And they are talking up even higher core counts next year probably 48 or 64 cores and twice the threads.
