Fix 32u with Wire end()

[hathach]

• use WIRE_HAS_END from arch AVR to detect whether wire has end(). This will work with both avr core that implement or not the wire end()
• Update: temporarily skip end() for esp32, which only implement end() starting from 2.0.1 (currently latest), this will give time for user to update their core (will enable later on). fix error: 'class TwoWire' has no member named 'end' #69
