Check OpenGL passed fences with glClientWaitSync()

This patch fixes an issue in the check of passed OpenGL fences.
Currently Dawn checks if an OpenGL fence is passed with glGetSynciv(sync,
GL_SYNC_CONDITION, sizeof(GLint), &length, &status), which always returns
GL_SYNC_GPU_COMMANDS_COMPLETE and is meaningless. This patch uses
glClientWaitSync() to check if a fence is passed instead.
