[PBrunot]

Description of Change

This change adds a new board lilygo-t-display based on esp32. Board variants have 4 MB or 16 MB flash memory. All boards come with a TFT display. This board is the predecessor to the already included lilygo-t-display-s3.

Tests scenarios

I have tested my pull request with a Lilygo TDisplay HW rev 1.1 by configuring PlatformIO to use the platform in https://github.com/PBrunot/arduino-esp32#feature-lilygo-tdisplay as framework for arduino-esp32, and uploading a sketch to a destination board successfully. Testing sketch is using serial, TFT display over SPI.

This is required to add support in platformio for the same board, as per platformio esp32 policies : platformio/platform-espressif32#209
