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.

Changes the memory management for the lvgl filesystem wrapper to use the
memory management strategy selected by kconfig. Additionally fixes memory
leaks if fs_{file,dir}_t initialization failed.
