Delete deprecated SetFirstChanceExceptionHandler function

Browse source 
This CL removes the code I marked as deprecated in
https://crrev.com/c/1411776. I could not delete the code in that CL
before I removed all uses in Chrome in https://crrev.com/c/1411643.

The tracking bug contains more information.
