[Role Logic Move] Lift user from Permissions::setAppOp

This change modifies the following methods:

- Permissions::setAppOpUidMode[AsUser]
- Permissions::setAppOpPackageMode[AsUser]
- Permissions::setAppOpMode[AsUser]

...by making them multi-user aware. I.e., lift any references to
Process.myUserHandle() out of them into method arguments.
