WeAct_STM32F405RGT6 flash with ST-Link

[WillxE]

Hi, i was able to do it on the f401_blackpill and it was running fine

now that im trying to flash tinyuf2 on WeAct_STM32F405RGT6 but it doesnt seems to show as flashdrive.

the board.h and board.mk are based on feather_stm32f405_express
and modified some parts

board.h
