Refactor DynamicIndexableContentMonitor
Refactor content monitoring code into a few singletons to keep alive
while Settings app is running.
Bug: 32995210
Test: Manually installing/uninstalling AOSP LatinIME.apk while
Settings app is/isn't running, then search AOSP.
Test: Connecting/Disconnecting Anker bluetooth keyboard while Settings
app is/isn't running, then search Anker.
Test: Added Robolectric test for DynamicIndexableContentMonitor.
