configureBinder method is unusable

[bclozel]

In AnnotatedControllerConfigurer.configureBinder, the accepted consumer is not really usable since the options builder received as an argument is immutable.
Maybe we should transform this consumer into a function or revisit this configureBinder contract altogether?

See spring-projects/spring-boot#50421

[bclozel]

After further thinking, GraphQlArgumentBinder.Options is immutable but solving this bug requires either:

• breaking source compatibility for AnnotatedControllerConfigurer.configureBinder and having a configureBinder(Function) instead
• making GraphQlArgumentBinder.Options mutable and keeping the existing API

I chose the second option.
