Subject: Allow to set the displayed item count and its alignment via meta
 (#8448)

* Allow to set the displayed item count and its offset via meta

* fix rect constr call

* devtest: add dump_item chatcommand

* fix rect2 constr call (sdim is a position (typedef for v2s32), not a dimension) and remove background because it would work now

* add missing utf8 to wide conversion

* rename to count_meta
