Add Record support

[hantsy]

Description

As a:

• Application user/user of the configuration itself
• API user (application developer)
• SPI user (container or runtime developer)
• Specification implementer

...I need to be able to:

Simply bind the properties to record class.

@ConfigProperties
record Range(int min, int max) {

   public Range{
     if(min < max) {
       throw IllegalArgumentExcpetion(...)
     }
   }

}

Scan @ConfigProperties class as CDI beans in Jakarta EE env, and inject it by type safely in other CDI beans

@Inject
Range range;

You can support records today on an ad-hoc basis using a custom Converter for each record type. For example, a Range record like you've given could be parsed using a regular expression like (-?\d+)\.\.(-?\d+), for values like "12..39" or "-20..20".

It would also be possible to generalize a converter that accepts values as a list of key-value pairs. Such a general record converter might allow values like min=123,max=456 or max=10,min=-1. This would likely be the best way to meet this use case with a generalized solution.

But in both cases, the entire record value would have to be encodable to a single configuration property. It would not be possible with the present architecture to spread a record-typed value across two or more properties.
