Improve readability of the insets related dump

This change improves the readability of the toString for the insets
related information, including:
1. Use understandable window type name, instead of the int value;
2. fix the indent issue of providedInsets and paramsForRotation;
3. When output InsetsFrameProvider, makes it one per line.

Besides, this also fixed the wrong indent of waitingForConfig and fix
several inconsistency in the output.
