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.

Compilation error "undefined reference to log_const_lvgl"
happened in lvgl_keypad_input.c when trying to get logs with
lvgl keypad module. Fixed by adding log level parameter
in log module macro.

Changes the default of `LV_Z_VDB_SIZE` to 100 percent if
`LV_Z_FULL_REFRESH` is set. Reason is that LVGL will reset the full
refresh flag if the buffer is not equal to the screen size.

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.

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.

Call lvgl_heap_init from lvgl_init rather than using two separate
SYS_INIT, this sensures that the heap is initialized correctly
regardless of the relation between CONFIG_KERNEL_INIT_PRIORITY_DEFAULT
and CONFIG_APPLICATION_INIT_PRIORITY.

Moves lvgl pointer driver handling based on kscan to its own file, to ease
deletion when the usage of kscan for display touch input has been
deprecated.

Add the scaffolding to create input lvgl pseudo devices which route zephyr
input_event to their lvgl `indev` equivalent. As a first cut also add a
`zephyr,lvgl-pointer-input compatible which can be a drop-in replacement
for the existing kscan solution.

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.

memory management strategy selected by kconfig. Additionally fixes memory
leaks if fs_{file,dir}_t initialization failed.
