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.
