Changed type evaluation behavior for protected instance variables (those that begin with a single underscore) and are assigned a literal value. Previously, the literal type was retained if the reportPrivateUsage was enabled. This caused various problems. It was a bad idea because type evaluations should not differ based on diagnostic reporting switches.

Improved member access logic to more faithfully match the Python interpreter's behavior when the member is assigned through a class, that member is a class itself, and that class has a metaclass that implements a descriptor protocol. It appears that the interpreter does not call through to the metaclass's __set__ method in this case, even though it does call its __get__ method when the member is accessed in the same circumstance.
...
Changed behavior of member accesses when the member is a class whose metaclass cannot be established (e.g. because it inherits from a class whose type is unknown). In this case, the previous logic returned an Unknown type for the member access. It now assumes that the metaclass does not implement a descriptor protocol, so it doesn't attempt to apply a descriptor access.

Sync from Pylance ( #2309 )
...
Rollup of:
- Update dependencies; TS 4.4, Prettier 2.4
- Explicitly handle unrooted execution environments (e.g., open file mode), preventing various crashes and oddities.
- Generate default values in method overload signatures. Previously, we didn't include them, which generated the wrong signature.
- Disable webpack caching (which recently broke upstream).
- Use attribute docstrings for type aliases in completion and hover.
- Clean up import resolver search path cache, which was leftover from the per-execution environment python interpreter removal.
- Modify parser to change the range of parenthesized expressions to their contents. This improves the ranges returned in hovers, document highlight, etc.
- Add boolean to ConfigOptions to check if the config was loaded from a config object (i.e., was produced in part by a `pyrightconfig.json` or `pyproject.toml` with a pyright section).
