base-modem: new method to wait for an explicit link port

When new link ports are created, the QmiDevice link management methods
try to make sure that the port exists in the system by the time the
link addition method returns, but that doesn't guarantee that the port
has also been notified by the kernel to ModemManager (e.g. via udev or
via kernel events).

This new method allows to do a explicit wait for a given port link; if
we already have it it will return right away, and otherwise we'll wait
for it to be notified via the "link port grabbed" signal.
