Validate paths like core does

Hi,

I have created #MR14 with the path validations. I have checked the functionality. Its working as expected. Let me know if anything else needs to be add here.

Thanks!

@nidhi27 looking great!

I left some comments. What about edge-cases? Is there anything we need to think about for URLs, like external URLs or anchor links (#)? Does that make sense for such cases?
External links don't make sense, I think? And Anchors?
Anything else?

Could you also add tests for the new functionality perhaps? And if it's possible and you have the time and coding fun, perhaps general tests in 📌 Write tests Active ?

Hi @Anybody,

Other than this, links can have query parameters. This is also getting verified here with anchor links(#).
I dont think external links is making sense here. Mostly front pages are inner pages and thats why we are checking it with "/" and if the url exist in drupal or not.

I think we can add all the test cases in https://www.drupal.org/project/front/issues/3438834 📌 Write tests Active to avoid any code conflicts.

Yes I agree, please prepare the tests and I'll pass this for review to Mr. clean code @Grevil :)
