Wire endTransmission() fix for issue #1725 (#1888)

* removed uint8_t Wire.endTransmission(uint8_t sendStop)

Having both endTransmission(bool) and endTransmission(uint8_t) creates problems.
There is no need for endTransmission(uint8_t)
endTransmission(1) and endTransmission(0) works with endTransmission(bool).
Removing endTransmission(uint8_t) allows the ESP32 code to be compatible with
all the other Arduino cores by allowing endTransmission(1) and endTranmission(0)
to work as it does on all the other cores.

* Wire library version bump for endTransmission() update
