This change introduces new fields on `lv_disp_drv_t` that allow to
specify the size of the full display and the offset of the display
subsection that is being rendered to. The values are used to transform
the drawing area before calling `flush_cb` so that only the desired part
of the full display is being rendered to.

If a child has pct width and the parent has LV_SIZE_CONTENT width, it results in a circular reference.
With fix zero content width is assumed for children in such case.
Besides if a child is center or right aligned the calculation of LV_SIZE_CONTENT might give in conter intuitive result.
To solve this center and right aligned children are not considered in LV_SIZE_CONTENT calculations.
The same applies for height.

This will simplify packaging recipes, it's not mandatory,
but there is no reason to have it as an option if it does
not imply any regressions.

* build: Add install rule
This can help to install lvgl on systems,
for clients applications.
It's made for unix (Linux OE/Yocto actually)
if needed it can be enabled for other platforms too.

* Create lv_example_chart_9.py
lv_example_chart_9.c was exactly what i needed, thanks for that one!
the only thing is, i needed it in MicroPython :-)
Here it is
* Update lv_example_chart_9.py
removed duplicate (... = lv.CHAR_POINT.NONE) lines
* Update lv_example_chart_9.py
restored gap
allocate_btn_areas_and_controls() returned very early if the same number buttuns were set
the the number fo rows can be different and is wasn't updated
fixes#2619
* feat(theme) add getter function for default theme
* fix(disp) set default theme also for non-default displays
