[Python] Run verifytypes on all generated SDK from spector

Expectations are to reach all of them at 100%. But let's start by checking if some of them are not already 100%.

Verifytype is a required CI check for Python repo, so when codegen regresses (like https://github.com/microsoft/typespec/pull/7119), it breaks service teams. We need to make sure changes we do do not affect the verify type score.

This issue is an engsys one, and it may create other issues based on troubles we find. We shouldn't close this issue until verifytype is actually enforced in the emitter CI with 100%.
