Add tft.enable flag, gate the use of ILI9341/STMPE610 on it.

- For esp8266 (lightswitch w/o touchscreen), set tft.enable=false
- For esp32 (lightswitch w/ touchscreen), set it to true.

Clean up mos.yml flags per architecture type.
- Button is always 0,2
- Relay0 at 16 for ESP8266, as that's NodeMCU v2's onboard LED.
- Relay0 at 13 for ESP32, as that's Featherwing's onboard LED
