Add "Unlocked device required" parameter to keys
Add a keymaster parameter for keys that should be inaccessible when
the device screen is locked. "Locked" here is a state where the device
can be used or accessed without any further trust factor such as a
PIN, password, fingerprint, or trusted face or voice.
This parameter is added to the Java keystore interface for key
creation and import, as well as enums specified by and for the native
keystore process.
