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.
