JDK-8302050 - Common state management for 3D implementation
Description
We dont have support for depth testing for 3D primitives and also we dont have appropriate depth texture which should be updated/cleared to maintain appropriate state. We need to add support for depth testing in Metal.

Also find appropriate test which can be used to verify depth testing in 3D.

Depth testing is verified using fx83dfeatures.TwoBoxes test from apps/toys/FX8-3DFeatures Also i modified this test to change dimension of boxes and z depth to check whether intersection in Z direction works fine.

At first i created depth texture by default when we create RTT texture and this also works fine, but i dont know its impact on performance. So after more analysis i am creating depthTexture when we setRTT. In future if we think it is better to create depthTexture along with RTT creation we should do it.
