Implement a Vulkan Allocator or use VulkanMemoryAllocator library

https://vulkan-tutorial.com/en/Vertex_buffers/Staging_buffer#page_Conclusion specifies:

It should be noted that in a real world application, you're not supposed to actually call
[vkAllocateMemory](https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkAllocateMemory.html) for every
individual buffer. The maximum number of simultaneous memory allocations is limited by the 
maxMemoryAllocationCount physical device limit, which may be as low as 4096 even on high end hardware like an 
NVIDIA GTX 1080. The right way to allocate memory for a large number of objects at the same time is to create
a custom allocator that splits up a single allocation among many different objects by using the offset
parameters that we've seen in many functions.

You can either implement such an allocator yourself, or use the
[VulkanMemoryAllocator](https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator) library provided by
the GPUOpen initiative.
