.NET 7: Add customizing the cookie consent value

[Rick-Anderson]

Customize the cookie consent value

• https://github.com/dotnet/aspnetcore/issues/40164
• https://github.com/dotnet/aspnetcore/pull/40213

I'm not sure the best place to document this. Add links to where we document it to the following:

• What's new in ASP.NET Core 7.0 preview
• EU General Data Protection Regulation (GDPR) support in ASP.NET Core
• Use cookie authentication without ASP.NET Core Identity
• Work with SameSite cookies in ASP.NET Core
• Share authentication cookies among ASP.NET apps

@Tratcher please suggest the primary doc to add this information.

@daviddesmet can you suggest where this should be documented?

[daviddesmet]

@Rick-Anderson I think it should be in EU General Data Protection Regulation (GDPR) support in ASP.NET Core since is related to the cookie consent.

There's a usage example in the issue https://github.com/dotnet/aspnetcore/issues/40164 I created which can be used as part of the documentation. I actually took part of the code from the GDPR docs to showcase the API usage.
