Importing FreeCAD as a module in a normal Python interpreter (e.g. /usr/bin/python3) stopped working with Python 3.12 (but works normally with Python 3.11). When executing "import FreeCAD as App", the interpreter crashes with "Fatal Python error: PyImport_AppendInittab: PyImport_AppendInittab() may not be called after Py_Initialize()".
The check that causes the error message and abortion was introduced in Python 3.12 via
7f3a4b967c
(and a typo in the error message fixed via)

This patch substitutes by isAttachedToDocument() (almost) everywhere where
getNameInDocument() is used for this purpose.
The very few places not touched by this patch demand a (just a little) less trivial change.
When we change the returning type of getNameInDocument() to std::string,
those places will be easily found, because they shall generate a compiler error
(converting std::string to bool).
Rationale:
The fact that getNameInDocument() return nullptr to indicate
that the object is not attached to a document is responsible for lots of bugs
where the developer does not check for "nullptr".
The idea is to eliminate all those uses of getNameInDocument() and, in the near future,
make getNameInDocument() return always a valid std::string.
Dramatic simplification of legacy code by separating code and data and applying some later C++.
Function removed from Application.cpp as it was in a anonymous namespace and could not easily be subjected to unit testing.
Added ProgramOptionsUtilities.h
Added new signal interface using boost::signals2 signalParamChanged.
Exposed to Python as ParameterGrpPy.AttachManager() to monitor changes
to all parameters, sub groups under the referring group.
Added new attribute for ParameterGrp(Py) to query the Parent and Manager
of the referring group.
* Change no need function newDocument("Unnamed") call to variant without parameter. "Unnamed" set in App newDocument function instead.
* Refactor New Document command to run without parameter.
* Translate new document's userName. Internal name = "Unnamed".
* Crowdin Add to updatets.py App.ts. Create new file App.ts
* Fix error where document name is set with one function parameter. In this situation set internal and user name to string variable. For default function call (without parameter) set internal name to Unnamed, userName = translate ("Unnamed")
