No class loading if Java features disabled

- No longer loads custom classes if not needed for respective packages
- Renames isGmsUnstable to isDroidGuardOrVending
- Removes spoofVendingSdk from migrate/autopif scripts (don't document yet)
- Adds missing setAccessible() call for early return in EntryPointVending.init()
- Adds missing set of spoofSignature -> 0 for vending
