[RFC][Validator] PHP-based configuration for Validator

[ajgarlag]

Description
Now that #37186 has been finally completed, I'd like to have a similar PHP-based format to configure Validator Constraints.

Actually, there are four ways to configure these constraints:

• Modifying the file containing the class to validate:
  • Using Annotations
  • Using a public static method
• Defining these constraints in external files:
  • Using YAML format
  • Using XML format

Could we have a PHP format to define these constraints in external files?

Will it be worth it knowing that PHP attributes are coming in 8.0 ? What I mean is: a lot of tools will be migrating annotations to attributes. Doing so is going full PHP. At that point creating a PHP way of declaring constraints could be easier I think ?
