[KeyEvent Mac] Remove the WebInputEventFactory from blink.

[KeyEvent Mac] Remove the WebInputEventFactory from blink.

The code has migrated into the chromium code base. See 
change https://codereview.chromium.org/1331013004/ for the 
chromium side change.

Only Mac used the WebInputEventFactory; the rest of the 
platforms had their code converted into chromium long ago.

nit: Make clear in CL description that this was really only the Mac impl
remaining, and link to the crbug.com/237267 for "burning this down"?
