pyright too slow to infer types from sympy functions

[denismazzucato]

pyright takes more than 12 seconds to infer type informations on sympy codebase. Not even setting useLibraryCodeForTypes to False could prevent pyright from exploring sympy as the library claims to be a typed library by including a py.typed marker file.

This means that using a project with sympy will make the editor extensions looking for type information return such in more than 10 seconds, killing completely the user experience.

See issue pyright#7159.
