Fix source-gen issue with a binding member access expression being on a separate line from the member expression

[layomia]

Same line

Interceptor location is successfully parsed. Project compiles:

var optionsBuilder = services.AddOptions<AppSettings>().BindConfiguration(nameof(AppSettings));

var optionsBuilder = services
    .AddOptions<AppSettings>().BindConfiguration(nameof(AppSettings));

Different line

Parsed interceptor location is inaccurate. Compilation fails with a CSC interceptors error stating that the generated [InterceptsLocation] points to an invalid location.

var optionsBuilder = services.AddOptions<AppSettings>()
    .BindConfiguration(nameof(AppSettings));

var optionsBuilder = services
    .AddOptions<AppSettings>()
    .BindConfiguration(nameof(AppSettings));

@captainsafia @eerhardt unfortunately this will affect the stage 2 showcase app.
