Add support for HostApplicationBuilder for JasperFXExtensions

[claudiu-mera]

Microsoft is moving away from Host.CreateDefaultBuilder and pushing the new way of bootstrapping applications via Host.CreateApplicationBuilder method.
Even thought Wolverine provides ApplyJasperFxExtensions for WebApplication approach, there is no support for the equivalent HostApplicationBuilder.
As opposed to WebApplicationBuilder , which exposes Host property for backward compatibility, HostApplicationBuilder does not expose it, making impossible applying JasperFX extensions.

Is this going to be supported?
