Manual fixes:
* mozurl/cbindgen.toml (including headers earlier)
* NetlinkService.h (forward-declaring a necessary struct)
* nsIWebSocketChannel.idl (forward-declaring OriginAttributes).
* nsAsyncRedirectVerifyHelper.h (forward-declaring nsIEventTarget)
* CapsuleEncoder.h gets a missing Capsule forward-decl.
* WebSocketConnectionBase.h gets some missing includes.
* HappyEyeballsConnectionAttempt gets some missing includes.
* nsUDPSocket missed nsSocketTransportService2.h for OnSocketThread().
* HttpInfo missed a forward declaration.
* MockHttpAuth missed an nsCOMPtr include.
* nsHttpAuthManager missed a forward declaration for nsIHttpAuthCache.
* WebTransportSessionProxy was using mozilla::Mutex in a member without
including it.
* win32 fixes to keep include order because windows headers suck.
* nsInputStreamPump needs an Atomics.h include.
