Replace permission-specific methods with package change callback.

This change replaces the following PermissionManagerInternal methods:

- revokeRuntimePermissionsIfGroupChanged()
- revokeRuntimePermissionsIfPermissionDefinitionChanged()
- addAllPermissionGroups()
- addAllPermissions()
- transferPermissions()

with a single onPackageAdded() callback, to ensure we have an API
surface that is generic enough for future new permission systems, and
exposes details that will remain absolutely necessary due to
compatibility.

We cannot use a generic package change callback because most of the
time, those callbacks should not be blocking the package changes -
however permission is different and needs synchronous callbacks.
Permission was tightly coupled with package manager, so that we need
to keep compatibility with the behavior that the permission state and
any permission changes will be ready right after package changes.
Meanwhile, permission is the only system component that needs this
level of integration with package manager so it doesn't make sense to
build a generic package change callback that may be misused by other
system components.
