Added new configuration setting called "defineConstant". It allows a configuration to specify one or more identifiers that should be assigned by pyright's binder to be constant anywhere they appear. Values can be boolean (true or false) or a string. If an identifier of this value is used within a conditional statement (like if not DEBUG:) it will affect pyright's reachability analysis for the guarded code blocks.

Fixed a bug that resulted in spurious type evaluation errors when certain circular dependencies existed between class declarations. When evaluated in certain orders, a class type was being partially constructed with a corrupt MRO. This type was then cached and used in subsequent type evaluation steps, resulting in false positive errors.
