Files opened by running `freecad xxxx.FCStd` or similar relative paths could not
be saved because of new code introduced to create parent directories. See
https://github.com/FreeCAD/FreeCAD/pull/4996#issuecomment-922370077 and
https://forum.freecadweb.org/viewtopic.php?f=13&t=62319&p=534156#p534156.
This commit resolves the issue by ensuring the parent path is absolute while
saving. We would probably like to make sure the file name is itself stored with
absolute path, but there's a few problems
1. There may be other occurences where files are loaded with relative paths. So
having a check here is a good idea.
2. Files opened by `freecad xxxx.FCStd` somehow don't have the issue where
renaming parent directory throws an exception on save. Instead the file is saved
in the new location.
* Fix lost filename in err msg
In some circumstances, FileExceptions are constructed empty, then have a
filename assigned to them, but the error message in these scenarios is
left as the default "unknown" one, which is sometimes shown to users.
This change fixes that case to be consistent with instances that are
constructed with the filename.
The exception can happen when trying to save the file in a location that does
not exist, or when the user does not have permission to write there. If it
comes when saving after closing the document, all previous changes can be lost.
Partially fixes issue #4098.

The FCGlobal.h can be included in a Global.h header file of an extension module.
The reason is that some IDEs (e.g. QtCreator) fails to detect the export/import macros when only defined in the PreCompiled.h files and thus raise a parser warning.
In these two cases, the project's file will not contain the latest
changes, so returning as if the save is complete is incorrect and can
lead to data loss (such as on app quit).
Found two memory leaks in class Enumeration
* method tearDown() always ignored to free the memory of the first element
* assignment operator didn't call tearDown() when needed
- this is necessary to perform electrodynamics simulations. Since the typical values are in the range of 1e6 S/m, we need the new units kS and MS
- since this is for simulations, also add electrical conductivity to the FEM material cards
+ add function to cleanup units and quantities in debug build
+ fix reference leak in PropertyVector::getPyPathValue()
+ fix reference leak in PropertyPlacement::getPyPathValue()
+ in InterpreterSingleton::init() use a static std::vector<wchar_t*> instead of a C array
to free memory at program end
+ in MainWindow::closeEvent() explicitly delete all task watchers
+ in ReportOutputObserver constructor pass parent to QObject
+ in PropertyEditor destructor explicitly delete QItemEditorFactory
