gallium/docs: fix up transfer description for 1d arrays, add cube map arrays 

Transfers always use z/depth for layers no matter if it's a 1d or 2d array
texture, we don't follow OpenGL's crazyness there. Luckily this appears to
only be a doc bug, everyone doing the right thing already.
While here also document z/depth parameter for cube map arrays.

v2: fix typo spotted by Eric Anholt

@ -472,15 +472,14 @@ The box parameter to some of these functions defines a 1D, 2D or 3D
region of pixels. This is self-explanatory for 1D, 2D and 3D texture
targets.
For PIPE_TEXTURE_1D_ARRAY, the box::y and box::height fields refer to the
array dimension of the texture.
For PIPE_TEXTURE_2D_ARRAY, the box::z and box::depth fields refer to the
array dimension of the texture.
For PIPE_TEXTURE_1D_ARRAY and PIPE_TEXTURE_2D_ARRAY, the box::z and box::depth
fields refer to the array dimension of the texture.
For PIPE_TEXTURE_CUBE, the box:z and box::depth fields refer to the
faces of the cube map (z + depth <= 6).
For PIPE_TEXTURE_CUBE_ARRAY, the box:z and box::depth fields refer to both
the face and array dimension of the texture (face = z % 6, array = z / 6).
