Use multi-field logs to log permissions

Before this change each permission+action combo had it's own ID. This
was very fragile and did not work for non-system permissions.

Now the action is the log-type and the permission is just a field in the
log.

Removed EventLogger test as all this test was supposed to do was
prevent issues with permission-action not having the proper IDs. This
obviously did not help.

Test: Used API 23 and API 26 apps to grant and revoke permission and
      confirmed logs are as expected
