Adding a memory pressure observer for ChromeOS.
This is a memory observer for ChromeOS which triggers the existing memory pressure listening objects to release memory.
Part of this code came from the old Athena project (see https://codereview.chromium.org/5113830031).
Note that all this code resides for the time being behind a flag.
