Changed the behavior when a parameter whose type is a "naked" TypeVar has a default argument value. Mypy doesn't allow this case. Pyright allows it but previously modified the parameter type to be a union of the TypeVar and the type of the default argument. This behavior closed some type validation holes, but it created other problems and was very unintuitive for users. See https://github.com/microsoft/pyright/issues/3130 . See https://github.com/microsoft/pyright/issues/2507 for a discussion that led to this original change. This change reverses this behavior. It potentially allows for some unsafe "creative" uses that will go unreported.

Changed protocol matching behavior for protocols that include a variable annotated as ClassVar. A class that defines this same variable as a "regular class variable" (one that is declared at the class level but can be overwritten on a per-instance basis) is now considered compatible with such a protocol.

Added special-case synthesis of the update method for a TypedDict class. For TypedDicts that include at least one read-only field, no updates are allowed. For TypedDicts that are writable, a "partial" type is synthesized that allows for any subset of keys (required or not required) to be passed to the update method.
