[starnix] Show ZX_INFO_MEMORY_STALL info in /proc/pressure/memory This CL makes starnix generate /proc/pressure/memory with real stats, including averages over the last 10/60/300 seconds, that are computed by Starnix according to data periodically sampled from Zircon. The a dedicated service (child of the Starnix runner) is responsible for keeping track of the averages and, in general, mediate access to the new PSI services. This provides an injection point for test. Indeed, a new integration test uses this method to feed known data to a puppet program running within Starnix instance and verify that it gets back the expected readings. Note: The ProcfsTest.ProcPressure test is now embedded in the new integration test, which tests the cpu and io PSI files too (the expectation being that in the future they will also be served over the same protocol, like memory PSI is today).
