anv: Use pass attachment information to insert flushes

Input and resolve attachments can cause an implicit dependency in the
pipeline.  It's our job to insert the needed flushes.  Fortunately, we can
easily reuse the usage tracking that we use for CCS resolves.

This fixes 159 Vulkan CTS tests on Haswell because we're now flushing in
between drawing and MSAA resolves.  I have no idea how they were passing
before on newer hardware.
