gl_rasterizer_cache: Texture view if shader samples array but OGL is not

When a shader samples a texture array but that texture in OpenGL is
created without layers, use a texture view to increase the texture
hierarchy. For example, instead of binding a GL_TEXTURE_2D bind a
GL_TEXTURE_2D_ARRAY view.
