…beMethodBase contains no method
they are no longer needed as ClassBase instances no longer hold Python references to themselves

…ype instances, unless they are per-alloc call no problem though - they will be collected by .NET garbage collector eventually
…cted directly instead. Also fixes event_rename domain reload test case
it should not be possible to construct an instance of a class that has been unloaded

… to allow them to be garbage collected
…ht shut down and unload corresponding methods before Python terminates

@filmor this seems to be working (at least tests are passing). The diff starts on top of pythonnet#1603 I wish it were smaller, but the old code that supported app domains for 3.8 and below just does not work for 3.9 and 3.10 (it made assumptions about internal GC data structures, that are no longer valid). |

pyHandleandtpHandlefields inManagedTypewhich used to make instances ofManagedTypeself-referential.ManagedTypenow providesAlloc, that creates a Python wrapper around the instance and returns a strong reference to it. That reference is explicitly passed around everywherepyHandlewas needed (usually asBorrowedReference ob).With reference loops gone (one notable exception is
PythonDerivedTypethat still requires it for .NET to be able to access Python implementation and vice versa), reference tracking is simplified. Lists of all wrapped .NET objects is stored inCLRObject.reflectedObjectsand all extension types inExtensionType.loadedExtensionsfor cross-domain support replacing "track types".PyObjectdisposal and finalization andPythonDerivedTypefinalization have been reworked to permit them when and only when both Python runtime and Python.NET engine are in appropriate states.A few minor bugs were fixed.
