Fixed a bug in the type checker that led it to conclude that two types were the same even though they were declared in separate modules. This occurred when the types had the same (local) name and both modules were located within project directories that contained characters that are invalid for module paths in an import statement (e.g. "-").

Increased the code complexity limit that controls whether pyright performs return type inference for functions that have no parameter type annotations. This can be quite expensive, and without parameter types, the results are often low quality. Beyond a certain point, we just skip the expensive analysis and infer a return type of Unknown. The previous limit was quite low. This increases the limit in an attempt to handle return type inference in more of these cases.
