  common: Add aligned memory allocator.
  
  This will be useful for the Vulkan pipeline state cache. This cache
  wants to pack the pipeline description very carefully into a specific
  number of bits, using the "alignas" keyword. Using this keyword
  requires an aligned allocator, which we can lift from Chromium's
  base/memory submodule.
  
  Also includes a unittest copied from Chrome.
