display: rename current BGR_565 format into RGB_565X

Browse Source 
The format currently expected by devices and sample display
application for BGR_565 is actually RGB_565 format with bytes
swapped (not B / R swapped). That is:

PIXEL_FORMAT_RGB_565:
         * @code{.unparsed}
         *   7......0 15.....8
         * | gggBbbbb RrrrrGgg | ...
         * @endcode

current PIXEL_FORMAT_BGR_565:
         * @code{.unparsed}
         *   7......0 15.....8
         * | RrrrrGgg gggBbbbb | ...
         * @endcode

This is explained in both st7796s display driver but also is
what is generated by the sample display application. As a video
format (ex: V4L2), such format is not mentioned as BGR (for
which R and B are swapped) but RGB_565X.

Within the whole Zephyr tree, rename the curremt BGR_565 format
into RGB_565X in order to emphasis that this is a byte swapped
format rather than a B/G component swapped format.

This also correct the description of the format in display.h
file, which wasn't correct based on what was being used by
display driver or sample display app.

* For ILI9341 controller, display mirroring configuration has been updated to conform with
the described behavior of the sample ``samples/drivers/display``. (:github:`99267`).

:c:macro:`PIXEL_FORMAT_RGB_565X` to correctly reflect that it is a
byte-swapped version of RGB_565, not a channel-swapped format.
