[Board]: Support for M5Stack Core2 ESP32 (Part 1: radio + display)

[lboue]

Adding support for M5Stack Core2 ESP32 because we no longer have an answer in PR #4471

• Part 1: radio + display

[caveman99]

Thanks for your contribution. Please see comments inline

I have ordered a copy of Core2 for testing. I should receive it next week.

I managed to make it work with the following setup:

LoRa Pin	Core2 GPIO
SPI_MOSI	23
SPI_MISO	38
SPI_CLK	18
RST	25
CS	27
IRQ	35
