Kscan coordinates are transformed in case display is rotated so that
frames of reference are aligned.

Add new Kconfig options to allow kscan axes swap and inversion. These
options are useful to align display and touch frame of reference. If a
touch API is ever introduced these options could be moved there.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

Align all Kconfig option names with LVGL names. The followed rule:
LV_(.*) -> CONFIG_LVGL_(.*).
Also replaced LVGL boolean configuration entries using if/else/endif
with direct IS_ENABLED macro.

Update LVGL to version 7.0.2. Notable changes in v7 include:
- New drawing system (note that it uses much more ROM than previous
versions)
- New style system
- Some objects have been renamed (current changes do not align yet
Zephyr Kconfig settings with LVGL)
- New fonts with more sizes (e.g. Montserrat, replacing Roboto)
- Theme changes (most have been removed, default is now Material)
Note that constant defaults have been aligned with LVGL.

Set actual display size, obtained via the display driver, when using
static rendering buffers. If the actual screen size is not set an
out-of-bound write could occur in case the maximum resolution settings
for LVGL are larger than the actual screen resolution.

Adds support for an optional lvgl touch input device using the zephyr
keyboard scan interface. This can be used with the ft5336 touch panel
driver, which returns single touch coordinates through the kscan
driver callback.

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.
Various generator scripts have also been updated as well as perf,
linker and usb files. These are
drivers/serial/uart_handlers.c
include/linker/kobject-text.ld
kernel/include/syscall_handler.h
scripts/gen_kobject_list.py
scripts/gen_syscall_header.py
