feat: Preliminary support for Python 3.13 (getsentry#3200)

Partial cherry-pick of: a98f660

Adding preliminary support for Python 3.13.

The `_partialmethod` attribute of methods wrapped with `partialmethod()`
was renamed to `__partialmethod__` in CPython 3.13:
python/cpython#16600

Starting from Python 3.13, `frame.f_locals` is not `dict` anymore, but
`FrameLocalsProxy`, that cannot be copied using `copy.copy()`. In Python
3.13 and later, it should be copied using a method `.copy()`. The new way
of copying works the same as the old one for versions of Python prior to
3.13, according to the documentation (both copying methods produce a
shallow copy).

Since Python 3.13, `FrameLocalsProxy` skips items of `locals()` that have
non-`str` keys; this is a CPython implementation detail, so we hence
disable `test_non_string_variables` test on Python 3.13.
