Move Max Contacts Reported below Contact Monitor in RigidBody inspector

This also changes the code used to hide the custom center of mass
property for consistency with other places in the editor
(only this approach worked for Contact Monitor as well).

The Center of Mass property hint in RigidBody2D was also modified
for better usability.
