Sema: Turn on availability checking by default

Browse Source 
Enable checking for uses of potentially unavailable APIs. There is
a frontend option to disable it: -disable-availability-checking.

This commit updates the SDK overlays with @availability() annotations for the
declarations where the overlay refers to potentially unavailable APIs. It also changes
several tests that refer to potentially unavailable APIs to use either #available()
or @availability annotations.
