nv2a: Handles depth borders in 3D bordered textures 

3D textures with texture borders have 4 layers of border on either side of the
content layers in addition to the normal 4 pixel border per layer. This change
handles those extra depth layers in roughly the same way that the per-layer
border texels are handled.

Fixes #1171
