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
ranges in the dcache, the method needs to be provided
via a lvgl_support.h file.

This patch adds the OSAL implementation of dynamic thread creation, mutex
and thread syncronization primitive (semaphore) enabling the use of the
parallel rendering architecture provided with LVGL 9.0. To use it, set
`CONFIG_LV_Z_USE_OSAL` and your preferred dynamic thread stack allocation
method (pool or heap).

This patch updates the module gluecode to be compatible with LVGL version
9.2. This includes changes done to display and input driver initialization
and draw buffer handling.

Use configdefault when enabling LV_COLOR_SWAP_16 within boards and
shield definitions, to avoid OR'ing the dependencies for the Kconfig
symbol. Otherwise, a user manually selecting LV_COLOR_DEPTH will
encounter build errors as LV_COLOR_SWAP_16 may be enabled when
LV_COLOR_DEPTH_16 is not selected

The LVGL flush thread was hard-coded to be cooperative.
For long-running actions like data transfer to the display,
this is problematic as it might block high-frequency actions like
USB or input events.
Hence, make it configurable to be preemptive, and rename it to match the
similar Kconfig values like CONFIG_SDL_THREAD_PRIORITY.

Adds the missing stubs for DMA2D kconfig symbol to fix the Kconfig warning
produced by checkpatch.

Add support for LVGL rounder callback function. Sometimes,
either the underlying display controller and/or the LCD host
controller might impose restrictions on frame resolution.
For instance, the E1394AA65A display model should impose that
either axis of a frame be multiple of 2 pixels or the Renesas
LCD controller of the DA1469x SoC, should impose that the
stride value, number of bytes between consecutive frame lines,
be multiple of 4 bytes.

Introduces a Kconfig symbol `LV_Z_LOG_LEVEL` because contrary to Zephyr the
numerical value of log levels in LVGL increases with severity. Also support
for the `LV_LOG_LEVEL_USER` is added.
Resolves issue #64351.

Enable offloading of display_write call to background thread for color
displays. This feature is opt-in, as it may offer significant
performance gains for every display pipeline.
When enabled display_write and lv_disp_flush_ready will be called from a
background thread. This means that while the display driver waits on the
hardware to render the framebuffer, the LVGL rendering thread will not
be blocked.
