Touchscreen component and driver fixes (#5997)

Browse source 
* Introduce calibration settings for all touchscreen drivers.
this will override the common values.
The x,y coordinates only calculated when the right calibrations are set.

* resolve issues reported by CI

* remove unneeded spaces and newlines

* Forgot to remove some obsolete code

* remove get_setup_priority from xpt2046

* remove media_player changes.

* media_player: removed to much,

* Update suggestions

* referd back the `get_setup_priority` removal so it can be moved into a othe PR.

* tt21100: restore init read

* fix spacing

* load native display dimensions instead of using internal dimensons.
and load it only onse on setup

* moved `update_touches()` to protexted section

* adding Clydes PR#6049

* add multitouch test script

* Update all Touchscreen replacing `get_*_internal` to `get_native_*`

* fixed some CI recomendations

* couple of fixes

* make sure the display is running before  touchscreen is setup

* fix clang

* revert back last changes

* xpt2046: change log level for testing

* logging information

* add test file

* fix polling issue with the for example the xpt2046

* fixed some CI issues

* fixed some CI issues

* restore mirror parameter discriptions

* same for the swap_xy

* same for the transform

* remove the above const from const.py

* and put  the above const bacl const.py

* Merge branch 'nvds-touchscreen-fix1' of https://github.com/nielsnl68/esphome into nvds-touchscreen-fix1

* and put  the above const bacl const.py

* [tt21100] making interupt pin optional

* [tt21100] making interupt pin optional (now complete)

* update the display part based on @clyde'
s changes.

* fix issue with ft6x36 touvhscreen

* reverd back touch check. add comment

* add some extra checks to the ft6x36

* add an other log and a typo fixed

* okay an other fix.

* add an extra check like others do
and fix data type

* [ft6336] fix update race when ts is touched.

* [touchscreen] update some log's with a verbose level.

* fix clang issues

* fix the clang issues

* fix the clang issues

* fix virtual issue.

* fix the clang issues

* an other clang issues

* remove anti-aliased fonts support. It does not belong here.

* remove anti-aliased fonts support. It does not belong here.

* rename test script

* Moving the test files to there right location.

* rename the test files

* clean up the code

* add a new line

* clang fixings

* clang fixings

* remove comment

* remove comment

* Update esphome/components/touchscreen/__init__.py
