Performance: Don't sort pageContext on Prod

[dajinchu]

Description

sortPageContext takes up 4% of CPU time on my medium-size project. Could we disable in prod mode?

Pre-released as 0.4.253-commit-a8f23e5.

No one has reported this so far, any ideas why it's slow on your side?

It's quite unexpected since it doesn't do anything costly. Unless you create a lot of pageContext properties, I wouldn't expect it to be slow.

Ran against test/vike-react project. sortPageContext takes up 2%. Not a huge penalty, but good to keep large chunks of main-thread CPU usage to a minimum in node.js.
