RFR: 8373232: Set default filters and addressing modes for 3D metal textures [v2]

[Jayathirth D V]

> Currently we don't set any texture filtering & addressing modes for 3D textures in Metal pipeline.
> Default 3D texture filtering is "nearest" for Metal textures, but we use "linear" filtering by default for 3D textures in case of OpenGL.
> Default addressing mode is "clamp_to_edge" in Metal textures, but we use "repeat" addressing mode for 3D textures in OpenGL.
> 
> Metal should use same default filtering & addressing modes for 3D textures as in OpenGL pipeline.
> Under this issue we are trying only to match defaults of Metal to OpenGL pipeline.
> 
> We don't update the filters/addressing modes for 3D textures once created.
> We have open enhancements like https://bugs.openjdk.org/browse/JDK-8324594 where we might provide API's to set sampler states for 3D textures in future.
> 
> Functional and performance testing is green with this update.
