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.

There are 4 Kconfig names about the "Draw Buffer". Rename 'VBD' to 'VDB'

config LV_Z_VDB_ALIGN

config LV_Z_VBD_CUSTOM_SECTION
bool "Link rendering buffers to custom section"
config LV_Z_DOUBLE_VDB
bool "Use two rendering buffers"
config LV_Z_VDB_SIZE
int "Rendering buffer size"
default 100 if LV_Z_FULL_REFRESH
And the draw buffer definition is now:

Adds support for the NXP PXP engine. LVGL changed
the Kconfig symbol from LV_USE_GPU_NXP_PXP to
LV_USE_PXP, but hal_nxp still relies on
LV_USE_GPU_NXP_PXP, so add a temporary symbol for it.
Additionally the drawing engines need to invalidate

For long-running actions like data transfer to the display,

similar Kconfig values like CONFIG_SDL_THREAD_PRIORITY.
