fix(lv_conf): get rid of the LV_CONF path building macros

so get rid of them, and instruct the user to define the symbol
as a string when configuring LVGL.

when defining the :c:macro:`LV_CONF_PATH`, you need to make sure it is
defined as a string, otherwise a build error will be raised.
If :c:macro:`LV_CONF_SKIP` is defined, LVGL will not try to include
``lv_conf.h``. Instead you can pass the config defines using build
