[WifiSettings] Submit Wi-Fi dialog with enter key

Add a OnKeyListener for hardware keyboards and an
OnEditorActionListener for on-screen IMEs to submit the Wi-Fi dialog
with the currently entered information.

Before committing the action, check for whether the dialog is
submittable -- that is checking whether all necessary information has
been entered. If not the enter key behaves the same as it is before
the change.
