      Description

      Commit 21ca13a5cd [1] introduces a bug in ConsumeWhitespace() function.
      When all chars in a string are white spaces, it should return string
      length. But current code returns 0. It's not noticed because x86 goes
      rapidjson simd code path which is okay. Arm64 now goes the buggy code
      path and triggers json unit test failure.
