Standardize watchdog messages

Try to stick to a common layout for watchdog messages:

- Skip leading "In " prefix.
- Identify "<type>::<method>".
- Ensure that all watchpoints around KeyMint invocations mention either
  "IKeyMintDevice" or "IKeyMintOperation" (to make it clearer when
  Keystore is blocked on the underlying KeyMint implementation).

Bug: 265778655
Test: watch logcat, add deliberate sleeps
