fix(ws2812-pwm): allow WS2812_PWM_TICK_FREQUENCY override (#26186)

Browse source 
Wrap the define in #ifndef so a keyboard's config.h can set it. The
default (CPU_CLOCK / 2) works for a fixed SYSCLK, but boards that
change SYSCLK at runtime (meletrix/zoom_tkl drops to 16 MHz on
battery) need a tick frequency that divides into both the high and
low TMRCLKs. Every other knob in the file is already #ifndef-guarded;
this one was the only flat #define.
