  Turn on vulkan backend for android ndk level < 26
  
  Fixes two issue for build Vulkan backend for android ndk level < 26,
  * Disable Vulkan validation layers for android ndk level < 26
  * Share vulkan memory allocator implementation with chrome to avoid
    duplicated symbols link errors.
  * Only run vulkan backend test with Android P or newer
  
  Note: This change will break android-binary-size try bot, we need to
  update expected_static_initializer_count to 4 at [1] while rolling this
  change into chromium.
  
      [1] https://source.chromium.org/chromium/chromium/src/+/master:chrome/android/static_initializers.gni;l=19?q=expected_static_initializer_count&ss=chromium%2Fchromium%2Fsrc
