Move webrepl support code from ports/esp8266/modules into extmod/webrepl (to be alongside extmod/modwebrepl.c), and use frozen manifests to include it in the build on esp8266 and esp32. A small modification is made to webrepl.py to make it work on non-ESP ports, i.e. don't call dupterm_notify if not available.
