Subject: [PATCH] mac: Add applicationSupportsSecureRestorableState

Requests that any state restoration archive be created with secure
encoding (macOS 12+ only). See https://crrev.com/c737387656 for
details. This also fixes an issue with macOS default behavior
incorrectly restoring windows after hard reset (holding down the
power button).
