🐛 [Bug] USE_PCH=OFF not working

[Stoabrogga]

I tried to turn off precompiled headers because I'm using ccache, but this leads to hundreds of compilation errors. The cause of this is the inclusion of "scriptPCH.h" in numerous core scripts. Precompiled headers should not be included anywhere because they are hiding the actual dependencies. Their sole purpose is to be used as a tool to reduce compilation time, which can be turned off if not needed.
