Suspending render pass jobs have more things than render targets to
preserve, e.g. occlusion query related information, atomic / compute
overlap enablement information etc.
Preserve them too when suspending. When resuming, for boolean
properties, or'ing them; for other preserved things assign them. This is
for ensuring the last resuming fragment job is compatible with all
suspending geometry jobs, as for suspending render passes the fragment
job is omitted.
The situation of the suspending render pass and the resuming render pass
have different query pools is still not supported, and quite difficult

The attachments field of the render pass state could be
MESA_VK_RP_ATTACHMENT_INFO_INVALID, which indicates no attachment
information is valid. If such situation really happens when initializing
the fragment state of a pipeline, this means neither a render pass nor a

the specificiation for that structure says colorAttachmentCount is
