add Ili9341 display (#1233)
* setup ili9341 framework
used epaper-waveshare as start

* first version working

* added models for now only M5Stack

* get_buffer_length is huge

* fill, low/high watermark, buffer tests failed.
RAM is to small for ili9341 16 bit color mode

* removed high/low watermark debug log

* added standard 2.4" TFT model

* code cleanup

* make ledpin optional
busy pin is not needed

* make bufer 1 byte to avoid the
buffer allocation error

* gitignore

* added backlight pin to dump_config

* huge speed increase
8bit color framebuffer (256 colors)
lo and high watermark for drawing to screen

* fix for images

* higher spi data rates

* Set spi data rate to 40Mhz Experimental

* fixed: formatting
fixed: the last row and column being trimmed
fixed: namings

* Update the code to use Color class

* fixed minor color things

* fixed linting

* #patch minor fixes

* fix gitignore too

* Update esphome/components/ili9341/ili9341_display.cpp

* reverting the changes as it's being fixed in PR-1241
