Add new physics elements for Nvidia PhysX #584

Desired behavior

I hope SDFormat would support the PhysX(Nvidia) as a physic engine so that I can utilize the standard format for robot simulation.

Since Nvidia PhysX introduced a new articulation body for robotics, and I think it's enough and possible to present the robot s in the world what we imagine.

refer to example here.

TGS is provided for solver in PhysX.

I guess many developers already know these feature in PhysX 4.0 but current SDFormat(even latest version) does not support that type in official. :(

Anyone have the plan to introduce a new physics engine type?

Implementation suggestion

describe any parameters related to PhysX ## Additional context Actually I'm working on open project which called [CLOiSim](https://github.com/lge-ros2/cloisim) to simulate the robotics simulation using SDFormat. I couldn't find reasonable SDFormat parsing library for C#, so I've created the parser by my self. And it implements the physics things like joint, inertial and whatever.. using the parameters in ODE type.

Adding specific elements for every physics engine hasn't been scaling well. I believe the direction we're planning to take is to use generic elements instead of engine-specific ones, see https://github.com/osrf/sdformat/issues/508.
