interfaces: drop the conditional import of the vendored `zope` packages...

interfaces: drop the conditional import of the vendored `zope` packages The real `zope` code was only used when enabled by a test, and the decorators turned into no-ops at runtime. Now that the test is disabled, unconditionally use the no-op decorators and stop importing the code. This module can go away once the `mercurial.interfaces.repository` interfaces are converted to Protocol classes, but the vendored code can be deleted in the meantime.
