PWM auto-phasing for lights by default (new behavior) unless SetOption134 1

[s-hadinger]

Description:

ESP32 only (including ESP32C3/S2)

You can revert to previous behavior (synced PWM) with SetOption134 1

Change in behavior for PWM. Until now all PWM phases were synced and started at the same time. This could cause increased stress on the power supply because the instantaneous power is high, even if average is low. This was also blocking from using H-bridge.

Now the default behavior is that each PWM pulse starts at the end of the previous pulse (yellow is PWM1, blue is PWM2). This also makes H-bridge possible as long as PWM1+PWM2 do not exceed 100% (possibly use LedTable 0 to disable gamma correction)

This feature also works for PWM inverted PWMi, the phase is based on the active part of the pulse (high for PWM, low for PWMi).

This feature has currently no impact on PWM (when SetOption15 0).

This PR also includes minor refactoring of PWM ESP32 functions to remove inlines.
