* lvgl_spi_conf: Define TFT_SPI_HOST even when no SPI is choosen
* lvgl_helpers: Let the SPI driver choose SPI DMA Channel
Use SPI_DMA_CH1 only on ESP32 target.
* lvgl_helpers: Move FT81X initialization to helper

Many code editors are set to do this automatically now, so it ends up being annoying to scrape back out of commits to keep them easily reviewable.
Also added '.DS_Store' and 'build' entries to .gitignore
Allows to not allocate a GPIO for display reset: some may have that pin tied or attached to a Power management IC.
Supersedes PR from @usedbytes doing same but only for IL9341, this is for all supported displays.
