delay / esp_delay: transparently manage recurrent scheduled functions (#8802)

Browse Source 
Recurrent scheduled functions will always be running in background.

esp_delay()'s interval (intvl_ms) is internally kept to its highest value allowing to honor recurrent scheduled functions requirements.

It transparently allows to keep with the arduino and nonos-sdk trivial programming way and still use background services or drivers running regularly.
