Method validation error handling by controller method parameter type

[rstoyanchev]

As described under #26219, in #26219 (comment) and #26219 (comment), when handling method validation errors, it's useful to know what it relates to, e.g. header name, cookie value, etc.

After #29825 and #30644 it is already possible to get a MethodParameter from each ParameterValidationResult and check parameter annotations. We can make it even easier to handle validation results for controller methods by method parameter type.

HandlerMethodValidationException now has a visitResults method that takes a Visitor to handle validation results by controller method parameter type.
