interfaces: convert the zope `Attribute` attrs to regular fields
At this point, we should have a useful protocol class.
The file syntax requires the type to be supplied for any fields that are
declared, but we'll leave the complex ones partially unspecified for now, for
simplicity. (Also, the things documented as `Callable` are really as future
type annotating worked showed- roll with it for now, but they're marked as TODO
for fixing later.) All of the fields and all of the attrs will need type
annotations, or the type rules say they are considered to be `Any`. That can be
done in a separate pass, possibly applying the `dirstate.pyi` file generated
from the concrete class.
The first cut of this turned the `interfaceutil.Attribute` fields into plain
fields, and thus the types on them. PyCharm flagged a few things as having
incompatible signatures when the concrete dirstate class subclassed this, when
the concrete class has them declared as `@property`. So they've been changed to
`@property` here in those cases. The remaining fields that are decorated in the
concrete class have comments noting the differences. We'll see if they need to
be changed going forward, but leave them for now. We'll be in trouble if the
`@util.propertycache` is needed, because we can't import that module here at
runtime, due to circular imports.
