Core/Scripts: Split script subdirectories into independent modules

* Makes it possible to define the linkage for every module
* Move the ScriptPCH into the root directory
* Changes the SCRIPTS cmake variable to a string type:
  -> -DSCRIPTS=0 is -DSCRIPTS="minimal-static" now
     (builds commands and spells statically)
  -> -DSCRIPTS=1 is -DSCRIPTS="static" now
     (builds all modules statically)
  -> -DSCRIPTS="dynamic"
     (builds all modules dynamically)
  -> Also the default value which is provided by the SCRIPTS
     variable is overwriteable through the SCRIPTS_COMMANDS,
     SCRIPTS_SPELLS... variable.

(cherry picked from commit 848b8a4136a4b395bfab74899520c74812d7f08e)
