RFR: 8327796: Add method to java.net.http.HttpRequest to return a GET request in one call [v5]

[Michael McMahon]

> Hi,
> 
> This PR proposes to add simple utility method which returns a simple GET HttpRequest in one call. The current builder pattern requires 4 (or 3 since GET is the default method) method calls to achieve the same effect.

> Thanks,
