bisect: move 'printresult' in the 'hbisect' module

The logic is already extracted into a closure. We move it into the module
dedicated to bisect.

A minor change is applied: the creation of the 'displayer' is kept in the main
command function, it remove the needs to import 'cmdutil' in 'hbisect'. This
would create an import circle otherwise.

      See :hg:`help revsets` for more about the `bisect()` keyword.

    Returns 0 on success.
