Subject: [PATCH] Resolve custom printer icon boundary exploit.
Because Settings grants the INTERACT_ACROSS_USERS_FULL permission, an exploit is possible where the third party print plugin service can pass other's User Icon URI. This CL provides a lightweight solution for parsing the image URI to detect profile exploitation.
Bug: 281525042
Test: Build and flash the code. Try to reproduce the issue with
mentioned steps in the bug
