Add multi-display support in Zephyr ontop of LVGL which already supports
it.
This change allows for creating buffers and structures for each display
statically and automatically from deviceTree info, and call LV init
routines for each display

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.

The LVGL input callback does not use an instance specific name, so we
can only ever have one instance of this type. This issue was evident by
a build error, e.g., when using "zephyr,lvgl-keypad-input" nodes twice:
error: redefinition of '_input_callback__lvgl_keypad_process_event'

For some systems, the display peripheral or GPU requires that buffers be
aligned on a boundary for optimal performance. We already align display
buffers using CONFIG_LV_ATTRIBUTE_MEM_ALIGN_SIZE, but some applications
will rely on the definition of LV_ATTRIBUTE_MEM_ALIGN. Provide this
definition so those buffers will be aligned as well.

Add a void *user_data pointer to the input callback structure. This is
useful for driver to get back the driver data structure and avoid
defining wrapper functions.

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.

Changes the Kconfig symbols for the sys_heap based memory management option
and removes the notion of `BLOCKS` with a more concise single
`LV_Z_MEM_POOL_SIZE` option. Also adds `LV_MEM_CUSTOM` to the lv_conf.h,
since in any option the memory management is considered to be custom.

Adds saving of the last lv_indev_data_t for button and pointer type
devices. This is needed because there is currently no way to tell LVGL in
the read callback that no event is pending. Preservation of the last state
is expected to happen in the port layer for the input devices.
This resolves issue #62512.

Removes the pseudo device prerequisite that the LVGL setup routine has been
executed before initialization. The pseudo devices are now registered at
the end of the LVGL setup routine, the driver is not concerned with
configuring the devices anymore. This also removes the need for enforcing
certain priorities within the same init level.
This resolves issue #62753.

Add a pseudo device which can be used to hook into qdec events and
optionally a button and relay the input_event to lvgl.
