Fix incorrect delay when setting WS2812 (and similar) leds (#9302)

Browse source 
* Fix incorrect delay when setting WS2812 (and similar) leds

* Add documentation for WS2812_DELAY_MICROSECONDS

* Remove improper cast to uint8_t

Co-authored-by: Sergey Vlasov <sigprof@gmail.com>

* Remove unneeded cast to uint8_t and correct math

Co-authored-by: Sergey Vlasov <sigprof@gmail.com>

* microseconds -> µs

Co-authored-by: Ryan <fauxpark@gmail.com>

* Make documentation better match the spec sheet.

Co-authored-by: Ryan <fauxpark@gmail.com>

* Rename macro to match spec sheet

* Further correction to the delay maths for the SPI case.

Co-authored-by: Joel Challis <git@zvecr.com>

* Move ws2812_common.h to the drivers directory

* Revert "Further correction to the delay maths for the SPI case."

This reverts commit e61b56a2cfc7dfec9992a7a3af92afa50e5b8ec0.

* Remove ws2812_setleds_pin(); consolidate ws2812.h
