In subpasses preserve attachments are not used by the subpass but
their contents must be preserved throughout the subpass.
Add a list for the preserve attachments info specified by a subpass
and when determining a subpass attachments total uses check the
preserve attachments list and add it uses to the total.

To avoid some circular dependencies due to pvr_private.h, split out
pvr_framebuffer etc into their own header.
We often only need to peek into the framebuffer, so this seems like a
good idea anyway. We can reconsider this once dynamic rendering has
landed, and we know how much remains here.
