Subject: [PATCH] Add change id for FLAG_SLIPPERY

We need to figure out whether any apps are using FLAG_SLIPPERY. Ideally,
we should lock this down and only allow it for system uses. Add a change
id for this logging here.

Bug: 157929241
Test: adb shell dumpsys platform_compat
Change-Id: I7a12828e768a145054d31fbf07f130a2f06735de
