MT5 translation for homedecor_common

- Remove intllib support
- Fix luacheck warnings (except for 1 I don't know what to do)
- Removes homedecor_common/mt_game_beds_functions.lua (we can get the
function directly from `beds` mod instead of using an obsolete copie; I
have not re-enabled bed-sleeping, but it should work)
