Make dyn idle startup increase configurable (betaflight#12432)

* Make dyn idle startup increase configurable

Replace fixed 5 percent max increase from dynamic idle
when airmode is active with a configurable value.

-Default value is still 5.0 percent (50 in cli)
-Add dyn_idle_start_increase cli setting
-Add dyn_idle_start_increase BB header field

* Increse PG reset to ver 6 for pidProfile

* Indentation
