[Backport] Fix unexpected diff between builds in generated/metadata directory

[ihor-sviziev]

Original Pull Request

#23325

Description (*)

Sort all path definitions before generating config and writing it to generated/metadata directory

This issue caused by using RecursiveDirectoryIterator object for generating list of all classes and all their arguments and it could return not sorted result. As result files between builds are different just because files were found in different sort order.

Hi @ihor-sviziev. Thank you for your contribution
Here is some useful tips how you can test your changes using Magento test environment.
Add the comment under your pull request to deploy test or vanilla Magento instance:

• @magento give me test instance - deploy test instance based on PR changes
• @magento give me 2.2-develop instance - deploy vanilla Magento instance

Hi @ihor-sviziev, my understanding is that 2.2-develop can live without this change. I'll review it for 2.3-develop this week.
