Don't store fortran objects in ScipyGer tag

[lucianopaz]

Description

This is a preliminary PR that hopes to address the various issues that came up around pymc with pickling fortran objects. For reference, here, here, here, and there might be more that I'm missing.

This is still a very early draft because I haven't built a reproducible code that shows the error, I hope to be able to do so next week. Once I do, I'll open a proper issue here on pytensor, add unit tests and promote this PR from its draft status.
