Hi,

After updating to macOS 14 (and rebuilding Emacs), I see the following
warning whenever I start Emacs:

    WARNING: Secure coding is not enabled for restorable state! Enable secure coding by implementing NSApplicationDelegate.applicationSupportsSecureRestorableState: and returning YES.

This patch does exactly what the warning suggests, and it silences the
warning.

TBH I'm not entirely sure I understand the implications of implementing
`applicationSupportsSecureRestorableState`.  IIUC it makes Emacs opt-in
to the "secure state restoration" mechanism in contrast to a former
(supposedly less secure) mechanism, but AFAICT Emacs doesn't opt-in to
state restoration in the NS port in the first place...
