A number of headers in the codebase included `rendering_server.h` just for
some enum definitions. This means that any change to `rendering_server.h` or
one of its dependencies would trigger a massive incremental rebuild.
With this change, we decouple a number of classes from `rendering_server.h`,
greatly speeding up incremental rebuilds for that area.
On my machine, this reduces incremental compilation time after an edit of
`rendering_server.h` by 60s (from 2m57s).
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.
