Vulkan: Faster FramebufferDesc compare Objects of this class are used as keys to a hash map and contain 10 serials. Prior to this change, operator== would compare all 10 serials. This change tracks the maximum index set and only compares up to that many serials. To make sure this maximum index stays low in the presence of depth/stencil attachment, this class stores the depth/stencil attachment's serial before the color attachments. The update API of the class is improved so this implementation detail is not leaked. This is in preparation for supporting resolve attachments, which would add another 8 serials to the class. With this change, the performance of cases that don't use resolve attachments won't be affected.
