  Log Message:
  -----------
  [Cocoa] NetworkSessionCocoa::createWebSocketTask creates up to 4 copies of the given URL request
https://bugs.webkit.org/show_bug.cgi?id=245711

Reviewed by Tim Horton.

Address a FIXME in `NetworkSessionCocoa::createWebSocketTask`; we clone the original URL request at
most once by instead lazily creating the mutable copy. This prevents us from needlessly copying the
request when two or more of the following are true:

- The protocol is non-null
- The request isn't app initiated
- Privacy proxy is disabled
- The main frame main resource was private relayed

No change in behavior.
