Review of suspend/unsuspend APIs

Clarified the package extras bundle returned from
getSuspendedPackageAppExtras.
Moved the bundle arg to the last in LauncherApps.onPackagesSuspended and
clarified the contents of the Bundle.
isPackageSuspended(String) now throws a NameNotFoundException if the
package is not found.
Also, removed a permission check from isPackageSuspendedForUser.

Test: builds, boots, existing tests:
atest com.android.server.pm.SuspendPackagesTest
