"bind" is ignored if annotated with not-registered type.

[hanjinliu]

Describe the bug

If an argument is intended to be provided by the "bind" option but at the same time annotated with a type that is not registered in the type map, magicgui fails to get values from the argument.

To Reproduce

This works.

def _provide_array(*_):
    return np.arange(10)

@magicgui(arr={"bind": _provide_array})
def f(arr):
    print(arr.mean())
f()

But this does not.

def _provide_array(*_):
    return np.arange(10)

@magicgui(arr={"bind": _provide_array})
def f(arr: np.ndarray):  # <--- annotation
    print(arr.mean())
f()

Expected behavior
It should work even with not-registered annotation.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• OS: Windows
• backend: PyQt5 5.15.9
• magicgui version 0.7.2
