  Vulkan: Support dumping VMA stats string
  
  This CL adds support for dumping the VMA stats string, which can be
  given to VmaDumpVis.py to visualize the allocations that the VMA has
  performed.
  
  To enable dumping the string, set:
  RendererVk.cpp
    rx::kOutputVmaStatsString = true
  
  Copy the desired JSON output into a text file, and pass that to
  VmaDumpVis.py:
  python3 \
    third_party/vulkan_memory_allocator/tools/VmaDumpVis/VmaDumpVis.py \
    -o stats.png stats.txt
  
  The legend for the visualization is available at:
  https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator/tree/master/tools/VmaDumpVis
  
  Bug: angleproject:2162
  Test: Manual verification
