  Vulkan: Drop support for VMA 2.0
  
    Since ANGLE and Chromium were last updated to use VMA 3.0, there have
  been no breaking issues so far.
    * ANGLE update: https://crrev.com/c/4777337
    * Chromium update: https://crrev.com/c/4911597
  
  Therefore, the support for the old VMA (2.3) can now be removed.
  
  * Removed ANGLE_VMA_VERSION from the build files, since they are
    no longer required.
    * Removed the VMA-related guards in the code as well.
  
  * Removed the flags and thresholds for the buddy algorithm, which were
    used in VMA 2.3.
    * Share group buffer pools is no longer a map.
