We're now using the Kconfig copied from the upstream lvgl repository. It
uses the LV_ prefix for all options while we're using LVGL_ for
Zephyr-specific ones. Make the latter consistent with upstream but also
make sure they're distinct from lvgl's by using LV_Z_ as the prefix.

This updates the lvgl in-tree glue code to work with version v8.1.0 and
bumps the west manifest accordingly.
The following are the most significant changes:
- The logging callback has changes in lvgl and no longer provides the
caller with an integer log level code. We now need to parse the log
string's prefix to determine the level.
- Several Kconfig options (mostly for default values of various settings)
have been removed because these values are no longer configurable in
lvgl.
- The library no longer performs a deep copy of the display and input
device driver structs, so these must no longer be allocated on the
stack in the init func.
Other than that it's mostly about renaming of various structures and
functions and adjusting the calls if function's signatures have changed.
This patch allows all in-tree users to work correctly but it's likely
it doesn't support all new widgets and layouts added in lvgl v8. These
however can be added gradually once this is upstream.

This should align with subsys/display which we do not have yet. Plan is
to move lib/gui into subsys/display.
