Reviewed by Chris Dumez.

Added a new WebContent.Crashy XPC process specifically to crash.  Safari, when running on internal builds will launch
a WebContent.Crashy depending on the canary base state.  A crashy WebContent process is launch immediately after
a WebContent for prewarming.  The UIProcess code will reap the crashed process without any impact on Safari.
This crashing process is used for internal testing.
