Revert "Implements more pack/unpack states. Pack: row length, skip rows, skip pixels. Unpack: image height, skip images, skip rows, skip pixels. Note that PBOs are not covered by this change."

Expectations still not correct. This removes suppressions for two
failing tests:

functional.texture.specification.teximage3d_depth_pbo.depth_component32f_2d_array
dEQP-GLES3.functional.texture.specification.teximage3d_depth_pbo.depth32f_stencil8_2d_array
