Add AzureB2C component

I think an AzureB2C component makes a lot of sense. this can than be handed over to the service with the `WithReference` and can be use with `AddAuthtication`. so basically this would create an b2c tenant on azure, create the appropriate app registraions and set all the needed configuraion like clientId, tenantId, policy names etc.

setting up b2c the correct way is often a pain a lot devs struggle with that. we could also add support for custom policies and if someone has a custom ui for b2c on another (react, blazor) project this could also setup the right setup for the identity framework experience files.

this could be bigger feature and might need some time planning beforehand.
