Description of Change

Closes #46109

Fixes an issue where calling Fetch.continueResponse via debugger with WebContentsView could cause a crash. Some light investigation showed that RenderFrameDevToolsAgentHost::{Connect|Disconnect}WebContents() relied on the primary main frame of the passed webContents to attach, but it might be the case that the RenderFrameHost at hand is not in its primary main frame. If the new RenderFrameHost is not the primary main frame, we don't want to reconnect otherwise we'll end up potentially trying to reconnect to a RenderFrameHost that already has a DevToolsAgentHost associated with it.
