M. Liebmann a307e806eb CLuaInstance: Add DynFonts for lua scripts

- You can create fixed-size fonts for use in Lua Scripts
 - The fonts are deleted after the script
 - The use of fonts is limited to the following functions currently:
   - RenderString()
   - getRenderWidth()
   - FontHeight()
 - Example in Lua scripts:
   Normal usage:
     local font = FONT.MENU
     RenderString(font, ....)
   Use DynFonts:
     Creates a font with height of 50px:
       local font = n:getDynFont(0, 50)
       local useDynFont = true
       RenderString(useDynFont, font, ....)
           or
     Creates a font in which the text("Example: xyz") has a width of 200px:
       local font = n:getDynFont(200, 0, "Example: xyz")
       local useDynFont = true
       RenderString(useDynFont, font, ....)

 - Set Lua api version to 1.13
