RTX - Fix for opaque materials being categorized as translucent. [OMPE-43859]

In previous versions, materials other than those shipped with Kit (such as MaterialX materials), could be categorized as non-opaque by the renderer, causing significant performance degradation.

There is a new setting, /rtx/material/omniRtxEnableOpacityOverride, which, when true, will by default set all these materials to be opaque.

If opacity control is required on a material, such as when using cutout opacity maps, the attribute bool omni:rtx:enableCutoutOpacity = true should be added to the Material prim.

Similarly, if the material is transmissive (e.g. glass), to render correctly in Real-Time 1.0, it should have bool omni:rtx:enableTranmission = true set on the Material prim. Note that this attribute has no effect in Real-Time 2.0 or Interactive modes.

Note that neither of these attributes have any effect in any mode unless the /rtx/material/omniRtxEnableOpacityOverride setting is set to true.
