Feature: support `@field.default` decorator for attrs

[yangdanny97]

Describe the Bug

Attrs allows setting a default factory for a dataclass field x by decorating a function with @x.default. I don't think we support this today

https://www.attrs.org/en/stable/init.html#defaults

Looks similar to x.setter/x.deleter for properties, so I imagine the implementation for that might be a good reference
