Fix original maps bottom layer (hacky) placed resources and artifacts

[Districh-ru]

Fix #8852

This PR fixes some issues for the original maps made by hack or some original editor bug when an action object is placed to the bottom player addons instead of the main main tile object.

It:

• reverts the implemented in https://github.com/ihhub/fheroes2/pull/6395 bottom layer to main object swap;
• fixes object type update for the case when an action object is placed to the bottom layer and the main tile object is not empty;
• fixes artifact type setting to correspond the shown artifact sprite when artifact is placed to the bottom layer.

Important! This PR fixes only the new games, not the saved games

Such map "hacks" can be observed on the map LOSTRELI.MP2 ("Lost Relic"). Master build (the picked up artifact is not the same as shown on the map):

I didn't really understand exactly where to look here :) In both cases, the artifact is hidden behind the trees, as it should be.

Hi, @oleg-derevenetz, in master build the current random artifact can have any sprite (according to the randomly given artifact ID) but the metadata[0] will always be 11 and the picked up artifact type will always be the "Mages' Ring of Power". Yes, it is hard to see but on the tile behind the forest there is some other artifact sprite, not the "Mages' Ring of Power":

Added: For the "Mages' Ring of Power" it will be:
