Generate overloads for queriable commands

[Muream]

Most likely there would be one overload per flag where the flag type becomes a bool and the return type becomes the initial flag type

Essentially, this:

def addAttr(arg0: str, longName: str = ..., attributeType: str = ..., minValue: float = ...) -> None:
    ...

Would become this:

def addAttr(arg0: str, longName: str = ..., attributeType: str = ..., minValue: float = ...) -> None:
    ...

@overload
def addAttr(arg0: str, query: bool, longName: bool) -> str:
    ...

@overload
def addAttr(arg0: str, query: bool, attributeType: bool) -> str:
    ...

@overload
def addAttr(arg0: str, query: bool, minValue: bool) -> float:
    ...

Note that the query flag isn't in the non overloaded function definition

These would have to be doubled up for q=True, unless you are only accepting the long form query=True

Yeah, I'm only including longname arguments in the stubs, those short names are the death of me haha

Just realized this might be trickier than this as some commands allow for multiple flags to be queried at the same time and there doesn't seem to be any consistent way to know that programmatically

One example is

def xform(*args: str, query: bool, translation: bool) -> [float, float float]: ...
def xform(*args: str, query: bool, translation: bool, worldSpace: bool) -> [float, float float]: ...

Ignoring this edge case for now might still be better than not having overloads at all though
