Change _timer_freq defaults. While muqss keeps its 100 Hz default just like tt stays at 1000 Hz, CacULE now defaults to 2000 Hz, and all other CPU schedulers will now default to 1000 Hz.

Reportedly, multiple games (mostly Unity based, but not only?) are seeing much higher CPU usage at lower tickrates resulting in degraded performance when CPU bound.
300 Hz and less are the worst offenders, but 500 and 750 Hz are also affected to some extent. CacULE is seemingly less efficient than everything else and needs 2000 Hz to keep up in those scenarios.

OS (kernel, CONFIG_HZ) 	Min 	Average 	Max
Arch Linux (linux, 300 Hz) 	81% 	91% 	96%
Arch Linux (linux-zen, 1000 Hz) 	21% 	25% 	42%
Fedora Linux (linux (Default), 1000 Hz) 	20% 	25% 	53%

1000 Hz isn't an issue on modern systems, but older or very weak CPUs (like Atoms) which aren't used for gaming might want to use lower values. Since our main target audience is gamers, it only makes sense to change the defaults here.
