mesa: Identify packed depth/stencil buffers using the Format field.
Intel sometimes uses packed depth/stencil buffers even when only a depth buffer or only a stencil buffer was requested. Common code currently uses the _BaseFormat field to determine whether a depth/stencil wrapper is necessary. But unless the user explicitly requested a packed depth/stencil buffer, the _BaseFormat field does not encode this information, and the required wrappers are not created. The problem was introduced by commit 45e76d2665b38b ("mesa: remove a bunch of gl_renderbuffer fields"), which killed off the _ActualFormat field upon which the decision to create a wrapper used to be made. This patch changes the logic to use the Format field instead, which is more like the old code. Fixes fdo bug 27590.
