Adds a per-device check for a 'best' queue family to use for present timing, rather than always using index 0. wsi_ext_present_timing holds resources (such as the command buffer) per queue family, rather than supporting only one. However, currently, only one queue family is supported at a time. In future, we can hook vkGetDeviceQueue calls to map VkQueues to their family index. Doing this will transparently give present timing support for multiple queue families. Signed-off-by: Alex Bates <alex.bates@arm.com> Change-Id: I5becb29dfc4a082e301031e0c693acd23eb95a51
