  Add utilities to get the Android backtrace
  
  * Added getBacktraceInfo(), which returns the backtrace information
    from the ANGLE code, including the addresses and the symbols if
    possible
  
    * Returns the data in an instance of the new class BacktraceInfo.
  
    * In order to access this function, backtrace_utils.h has been
      included in vk_utils.h
  
  * New GN flag to make use of this feature:
  
    * angle_enable_unwind_backtrace_support
  
      * Current only available on Android (debug mode)
  
    * If the flag is disabled, getBacktraceInfo() returns an empty
      object.
  
  * Added functions in util/ (per platform) to print the BacktraceInfo
    data.
  
    * Example of usage:
        angle::printBacktraceInfo(angle::getBacktraceInfo());
  
  * Minor edit: Moved cstdint from android_util.cpp to its header.
