Revert "Add a DumpWithoutCrashing to RPHI::ProcessDied"

This reverts commit b8079095.

Reason for revert: DumpWithoutCrashing no longer needed

Original change's description:
> Add a DumpWithoutCrashing to RPHI::ProcessDied
> 
> After some discussion of a bug in webview that detects "abnormal"
> renderer process terminations, this failing DCHECK may be the cause. So
> add a DumpWithoutCrashing and see if it gets and if so, what the stack
> is.
