This was accidentally broken by #9627 because during config sync, a config validation happens that uses `--define System.ZonesStageVarDir=...` which fails on the now frozen namespace. This commit changes this to use `Internal.ZonesStageVarDir` instead. After all, this is used for internal functionality, users should not directly interact with this flag. Additionally, it no longer freezes the `Internal` namespace which actually allows using `Internal.ZonesStageVarDir` in the first place. This also fixes `--define Internal.Debug*` which was also broken by said PR. Freezing of the `Internal` namespace is not necessary for performance reasons as it's not searched implicitly (for example when accessing `globals.x`) and should users actually interact with it, they should know by that name that they are on their own.
