Wire.requestFrom with 5 params is undocumented & exists only on AVR & SAM, not SAMD & megaAVR

Looks like a requestFrom() function taking 5 parameters is undocumented, and only implemented in 2 of the 4 platforms Arduino supports.

Here are the definitions in the AVR and SAM platforms:

https://github.com/arduino/ArduinoCore-avr/blob/master/libraries/Wire/src/Wire.h#L63
https://github.com/arduino/ArduinoCore-sam/blob/master/libraries/Wire/src/Wire.h#L49

However, the SAMD and megaAVR plaforms only have the 2 and 3 parameter requestFrom() functions in their Wire libs:

https://github.com/arduino/ArduinoCore-samd/blob/master/libraries/Wire/Wire.h#L45
https://github.com/arduino/ArduinoCore-megaavr/blob/master/libraries/Wire/src/Wire.h#L60

The Wire library requestFrom() reference page also only documents the 2 and 3 parameter functions:

https://www.arduino.cc/en/Reference/WireRequestFrom

This 5 parameter function should be properly documented, and should be consistently implemented on all platforms. Perhaps issues need to be opened on the repositories for the SAMD and megaAVR platforms?

比较链接的 AVR、SAM、SAMD 和 megaAVR core 的 Wire.h 文件中的 requestFrom() 声明，然后查看 Wire requestFrom 参考页面。确定跨平台五参数 API 的预期范围；当受支持的行为得到一致实现且参考文档涵盖该行为时，即视为完成。
