Vulkan: Remove type indices with host-visible bit Currently, the memory type index for VMA image allocations are selected and returned by the API. However, it could potentially choose a type index with more flags than required or preferred, and ignore the index with exactly the flags we want. For example, it could pick a type index with the host-visible property flag, even if is unnecessary and a type index with a device-local flag would suffice. Using memoryTypeBits during the allocation allows us to filter the unwanted type indices out and use the other indices initially. * Added a new function to RendererVk.cpp to try to remove the memory type indices with the host-visible bit for VMA image allocations if they should be device-local. * GetMemoryTypeBitsExcludingHostVisible() * It also removes the indices with the protected bit if it is not required. * If the allocation is unsuccessful, the fallback resets the field for memoryTypeBits, allowing all available type indices to be used for the allocation. * Added memory type index to the pending allocation log during OOM.
