anv: add transfer usage for color/depth/stencil attachments 

We sometimes use anv_layout_to_aux_state() to compute the aux state of
an image during the resolve operations at the end of a render
(sub)pass.

If we're dealing with a multisampled image that is created without a
transfer usage, our internal code might trigger a resolve using the
transfer layout (see genX_cmd_buffer.c:cmd_buffer_end_subpass), for
which the image doesn't the usage bit. The current code tries to AND
the 2 usages which won't have any bit in common, thus skipping all
checks below.

v2: Add the transfer usages depending on attachment usage (Lionel)

v3: Limit to samples > 1 (Jason) && DEPTH_STENCIL_ATTACHMENT_BIT (Lionel)

v4: Add transfer usage at image creation (Jason)
