Work-around for system property failures

Bug: 236932163

This change adds a work-around to PropertyInvalidatedCache for
failures to set a system property.  Such failures cause fatal crashes
in Android but it is believed that a simple retry will succeed.
(Note: the failures have only been reported on partner devices and
cannot be reproduced on Pixel phones, so no root-cause is available
yet.)

RuntimeExceptions (thrown from android_os_SystemProperties.cpp) are
caught and retried.  The retry limit is 5 times with a 200ms delay
between attempts.  This means that the maximum delay is 1s, whcih
should avoid triggering an ANR.

In addition to automated testing, a manual test was created with
ambush code in the system property component of libc.  The ambush code
injected an error into the set-property logic for cache keys.  It was
observed that the system recovered properly.

Test: atest:
 * FrameworksCoreTests:PropertyInvalidatedCacheTests
 * FrameworksCoreTests:IpcDataCacheTest
