6 security fixes

Summary

Primarily works the WebKit/WebCore process-boundary layer — Site Isolation plumbing, IPC message handling in NetworkConnectionToWebProcess and WebResourceLoader, and a steady stream of StabilityTracer crash fixes for invalid-message terminations. The security work is tightly clustered rather than scattered: nearly every flagged fix is a missing `allowsFirstPartyForCookies` check on an IPC entry point (loadPing, WillSendRequest reply, startDownload/convertMainResourceLoadToDownload), with an unvalidated `replacementPath` in `registerInternalFileBlobURL()` alongside it — the same class of bug found repeatedly in adjacent handlers. Systematic-variant candidate: enumerate the remaining NetworkConnectionToWebProcess IPC handlers that take a frame/page identifier or a filesystem path and check which ones still skip origin validation.
