Fix inference autocomplete

[jhamon]

Problem

While implementing lazy loading and a package level .pyi file, we accidentally broke intellisense for some classes.

Solution

• Add missing exceptions to pyi
• Remove type annotations on pc.inference that rely on values imported during TYPE_CHECKING. It seems like mypy and intellisense/autocomplete are able to infer these types without them being labeled explicitly. I think there is some sort of bug in the way autocomplete works because these type hints used with TYPE_CHECKING are valid and seem to work for typechecking purposes.

Type of Change

• Bug fix (non-breaking change which fixes an issue)

Test Plan

Made a 7.0.1.dev1 dev build to confirm autocomplete behavior in different environments
