Lua: Add read access to Topic info Conditions

We already have a lot of access to check if a topic is available thanks to #7964 (closed)

What's currently missing are those Info conditions like

{function = "Journal", Variable/Object = "MV_OutcastAshlanders", relation = ">=", Value = 30}

{function = "Not Local", Variable/Object = "NoLore", relation = "=", Value = 0}

etc

Access to the script Text would be nice too (edit: already exposed, just the normal scripts aren't yet)
