Added support for VMA_ALLOCATION_CREATE_PERSISTENT_MAP_BIT without HOST_VISIBLE.

Implemented usage of VK_KHR_dedicated_allocation.
Renamed "own allocation" to "dedicated allocation" everywhere.

@ -41,6 +41,7 @@ Additional features:
- Customization: Predefine appropriate macros to provide your own implementation of all external facilities used by the library, from assert, mutex, and atomic, to vector and linked list.
- Support for persistently mapped memory: Just allocate memory with appropriate flag and you get access to mapped pointer.
- Custom memory pools: Create a pool with desired parameters (e.g. fixed or limited maximum size) and allocate memory out of it.
- Support for VK_KHR_dedicated_allocation extension.
- Defragmentation: Call one function and let the library move data around to free some memory blocks and make your allocations better compacted.
- Lost allocations: Allocate memory with appropriate flags and let the library remove allocations that are not used for many frames to make room for new ones.
- Statistics: Obtain detailed statistics about the amount of memory used, unused, number of allocated blocks, number of allocations etc. - globally, per memory heap, and per memory type.

<li>Only allocations made in memory types that have <code>VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT</code> flag can be compacted. You may pass other allocations but it makes no sense - these will never be moved.</li>

memory blocks (as if you explicitly used VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT
flag) when it is recommended by the driver. It may improve performance on some

supported, you enabled them while creating Vulkan device passed as
VmaAllocatorCreateInfo::device, and you want them to be used internally by this

- VK_KHR_dedicated_allocation

VmaAllocatorCreateInfo::pVulkanFunctions and fill at least members:
VmaVulkanFunctions::vkGetBufferMemoryRequirements2KHR,
VmaVulkanFunctions::vkGetImageMemoryRequirements2KHR, because they are never
imported statically.
When this flag is set, you can experience following warnings reported by Vulkan
validation layer. You can ignore them.
