Vulkan: Fix format properties queries When querying format properties (in vk::GetFormatProperties), the mandatory feature support table was consulted to check whether a number of texture features are present. If so, the entry from that table was returned. The goal had been to speed up initialization by not issuing device queries if possible. That is, when vk::GetFormatProperties was called on a format, if it supported that select few texture features, the VkFormatProperties entry from the mandatory table would be returned. However, that function found its way to other uses (such as querying buffer format properties, or other image properties beyond the select few). As a result, when the VkFormatProperties from the mandatory table was returned, actual support for these other features was often not tested and assumed false (unless they happened to be mandatory as well). This commit reworks the format feature query functions such that the specific features to be tested are provided when querying the format properties. The mandatory table is consulted as before, and if the entry doesn't contain those features, the device is queried and the results cached.
