Simplify NIBBLE encoder code and clean up keymaps (#11808)

* Simplify encoder code and clean up keymaps.

-Removed overly complex VIA encoder code. It wasn't adding any value and was confusing users who were trying to customize encoder functionality on VIA keymaps.
-Replaced KC_TILDE with KC_HOME in all keymaps, as KC_TILDE sends a left shift, which was confusing some folks as they tested their build.
-Move layer names to enum

* Change encoder_update_kb to encoder_update_user per PR feedback

ws2812: Fix number of nops for AVR at 8 MHz (#9559)

* ws2812: Fix number of nops for AVR at 8 MHz

When trying to calculate the number of nops for AVR running at 8 MHz,
the value of `w3` is expected to be negative; however, because `F_CPU`
is defined in tmk_core/avr.mk with the `UL` suffix, the preprocessor
performs its calculations using `unsigned long`, getting a very large
positive number instead of the expected negative number; this then
results in generating code with a huge number of nops.  Fix the broken
calculations by performing a comparison before subtraction, so that the
unsigned number wraparound does not occur.

The keyboard which triggers the problem is `handwired/promethium`; the
buggy code silently compiles, but the resulting timings would be
completely wrong.

* ws2812: Clean up the code after the 8 MHz fix

Remove old code which was unsuccessfully trying to clamp negative w1, w2
and w3 values to 0, and set w1_nops, w2_nops and w3_nops directly.
