Feat/orderform same site cookie

[Mecrano]

What problem is this solving?

Many stores need to be inside an iframe, this is only possible if the orderform cookie (checkout.vtex.com) has the SameSite='None' property set, an option was created in the app configuration to enable this feature, by default it is set to false to keep the stores that do not need this feature unaffected.

How to test it?

1. Link the application
2. Set the SameSite='None' flag to true through the administrator.
3. See how the cookie property changes.

Hey @Mecrano. Can you provide a linked worskpace for testing purposes? I also recommend the @vtex-apps/checkout-team to take a look at this PR

@Mecrano Our security team recommended not moving on with this change due to it being a potential security risk. I'm closing this PR.
