`from_type` on `typing.Protocol` without methods about hypothesis

[Zac-HD]

• Your NoMethods protocol is not actually runtime-checkable (because it has non-method attributes), so Hypothesis can't handle this at runtime. Unfortunate, but nothing we can do there.
• from_type() successfully generates instances of the bare class - the fact that this doesn't actually ensure that the x attribute exists is not Hypothesis' problem.
• @dataclass generates an __init__() method which takes a float x and assigns it to an attribute, so this works.

An internal _from_protocol() strategy to use for non-runtime-checkable protocols would be technically feasible, but providing objects with no useful behavior which technically satisfy the protocol just doesn't seem very useful to me.
