Fixed a bug that led to a false positive error about an "unknown type" in certain cases when using an assignment expression (walrus operator) in a loop. This addresses https://github.com/microsoft/pyright/issues/4557 .

Addressed performance issue in code that includes loops and many interdependencies between variables with inferred types. The optimization involves the introduction of an incomplete type generation count that is updated when a the type cache is updated in a way that could affect previously-calculated incomplete types. This addresses https://github.com/microsoft/pyright/issues/4231 .

Disabled type narrowing for expressions of the form "<literal> == X" and <literal> != X". These were never documented to work, and they were causing significant performance issues. Also reverted recent attempt to modify the code complexity algorithm, as this change is no longer necessary. This addresses https://github.com/microsoft/pylance-release/issues/3886#issuecomment-1410116374 .

Modified overload matching algorithm to more closely match that of mypy. In the case where one or more arguments evaluate to Any but those arguments map to parameters whose types are the same, the first overload is selected. Only in cases where an Any argument produces ambiguous results is an Unknown result produced. This addresses https://github.com/microsoft/pyright/issues/4546 .

* Changed hover provider to limit its display of overloaded functions when hovering over a name that is part of a call expression. In such cases, the context of the call's arguments often provides sufficient context to select one (or in some cases, several) overloads.
* Added unit test for overload-aware hover capability.
