  Change angle_util to be a shared library
  
  So that there will be one instance of static thread synchronization variables
  in AndroidWindow.
  Previously there was one instance in lib_angle_deqp_gles2_tests__library
  and one in libangle_deqp_libgles2, resulting in AndroidWindow::initialize
  waiting forever.
  
  Also make the change in GYP build to fix standalone build,
  and fix rpath issues on Mac.
  
  BUG=angleproject:1471
  TEST=end2end and deqp tests on standalone Win10 and end2end on GN Mac 10.11
