Subject : Remove runtime flag 'UnsafeES3APIs' from blink webgl.
Author  : yunchao.he
Commit description:
  
This is the first step to remove unsafe mode and enable
ES3 APIs for WebGL2 and ES3 context by default.
Command line option "--enable-unsafe-es3-apis" would be
unnecessary and removed afterwards.

Intent to implement:
https://www.chromestatus.com/features/6694359164518400

Launch bug:
http://crbug.com/641635
(Note that this is not the launch CL -- it's still not possible to create a WebGL 2.0 context without the flag)
