Initial work for Heltec Vision Master 213 (#4286)
* Fix for serial monitoring and I2C for Vision Master e213 (#4280)

* Fix for serial monitoring and I2C

The board did not allow serial monitoring while on boot mode, i was able to fix this by adding a board variant. I also corrected the i2c pins. I was able to test it with a cardkb

* oops

I delete some code by mistake, all back now

* Made some adjustments

* Minimize the diff

* Don't redefine board identifier
Suppresses compiler warnings

* Detect Vision Master 213 with PIO serial monitor

* Use outermost button as user-button
Less chance of accidentally hitting reset

* Use 1200bps touch (213)
Allows upload without manually entering bootloader
