Enhancement: Added code to interpret the python.path VS Code setting in the same manner as the Python VS Code extension. In particular, it now handles the special-case value of "python" to mean "use the default python interpreter" rather than treating it as a relative path.
Enhancement: Added special-case handling of __import__ built-in call so it always returns Any type.
Bug Fix: Fixed bug in code that determines whether code is reachable.
Bug Fix: Fixed static expression evaluation for expressions that involve python platform when no platform is specified.
Bug Fix: Fixed bug in alias resolution logic that caused the definition provider not to take the user to the right location in cases where there were multiple alias hops.
Bug Fix: Changed implicit module symbol __path__ to be properly typed as Iterable[str] rather than str.
