Remove forwarded kwargs docs from Parameter class docstring

Remove documentation for instrument, max_val_age, vals, and
bind_to_instrument from the Parameter class docstring since these
are not explicit parameters but are forwarded via **kwargs to
ParameterBase. The **kwargs entry already references
ParameterBaseKWArgs for details.
