Remove useless SG_BASES declaration for PyObject.
This won't compile after upcoming changes to BaseInfo.

Delete PyAthenaGILStateEnsure.h and use the copy from RootUtils instead.

Use DeclareInterfaceID/extends.
Clean up a bit.

Update for headers moved from SGTools to AthenaKernel.

In an MT job, we need to always make sure we're holding the python GIL
before calling any python code.  There's a utility in this package
that does exactly that, but it was private to this package.
Make it public, so it can be used from other packages as well.
