Add board LilyGo T3-STM32

• Vendor: LilyGo
• Product page: https://lilygo.cc/products/t3-stm32
• More information (schematics, sample code, etc.): https://github.com/Xinyuan-LilyGO/T3-STM32

Serial upload will not work until PlatformIO stm32flash is updated to include this upstream commit: https://sourceforge.net/p/stm32flash/code/ci/5530160c67df46c0fff9dcdeb46585b1c8512140/

As a workaround, flash the built .hex file using STM32CubeProgrammer (or use upload_protocol = stlink).

Hi @ndoo, it seems that this board is not supported in Zephyr framework. Also, please double check if the J-Link device name is correct.
