Renaming and extending the ili9341 to the ili9xxx component (#4275)

Browse source 
* - Removed cleaning the screen twice.
  \Should be handled by  `DisplayBuffer::init_internal_();`
- Made ili9341::initalize() protected and renamed
  \ it to ili9341::initalize().
- ili9341::initalize() should only init the display
  \ and set the width and heigth.

* removed to much

* clang format fixes

* removing trailing underscors for
protected virtual methods

* removed the "override"  on display()

* clang fixes

* restored old changes

* Renamed the ili9341 platform to ili9xxx and added
multiple drivers as well. including PR #3848

* fixed most of the clang reported issues

* fixed reported issues

* last fixes

* Setting the right codeowners

* missing changes

* fixed naming Display() method.

* clang again

* clang fix

* fixes reported by @jesserockz & @gpambrozio

* a change to display.py removing an unneeded var

* re-introduce **backlight** option.

* update the ili9488 initialization

* update the ili9488 initialization and fix typo

* fixed typo

* add missing constants

* swap height and width back for the ili9488

* init fixes ili9488

* fixed lint issue
testing the init code

* oeps

* init fixes ili9488

* fixed wrong define

* fixed wrong define again

* removed some spaces

* revert to ili9341

* Remove parts that where used for
the switchplate

* lint fixes and removing unused function

* fix error and introducing 16bit color option

* fix error and introducing 16bit color option

* fix clang issue

* clang fix

* clang issue again

* is this what clang exprect

* clang fix

* clang fix

* try again

* let try again

* and again

* and the last clang fix

* remove the need of wifi

* update dimentions

* update ili8488 init code.

* update dimentions

* allow to change height and width

* dump color mode config

* fix

* fix

* modify logging

* referd back unrelated change

* code formatting commit and moving functions around

* add missing ;

* update code

* update code

* use the correct write_array for sending uint16_t

* fix panic loop

* fix panic loop

* - update the test file
- fixed sending display data

* clang fixes

* clang fixes

* clang fixes again

* remove .gitignore items

* remove .gitignore items

* make sure Update() can can not be called while
called

* clang correction

* adding a test yaml for the ili9341

* Update ili9341 example

* Make test ili9xxx/tests only local

* restore back old ili9341 driver code

* Add a new config for the M5Core

* fix clang request

* reverd to restore of the old ili9341
there is no proper way to say it is depricated.

* Remove the backlight/led pin from the config.
You need to use a proper light platform component

* Ili9488init changes (#88)

Fixed ILI9488 init settings, and adjusted pixel handling code to push pixels in 18 bit format.
This does not change the internal 16-bit representation.

* fixed some leftover clang issues from the merge.

* fixed the slang-tidy request.

* remove `backlight_pin` warning.
