[GEN][ZH] Fix black terrain in World Builder without RTS_DEBUG

[xezon]

• Fixes Terrain renders black in World Builder #1186
• Partially fixes [ZH] World Builder behaves differently when built with RTS_BUILD_OPTION_DEBUG enabled #1116
• Merge after [CMAKE] Remove obsolete interface libraries, add missing core gameengine include interface library #1036

This change fixes the black terrain in World Builder without RTS_DEBUG. This issue happens because all code around GlobalData::m_shroudOn is compiled out without RTS_DEBUG, which enables shroud and turns the world black.

TODO

• Rebase after [CMAKE] Remove obsolete interface libraries, add missing core gameengine include interface library #1036 is merged
• Replicate in Generals
