Make DiscoveryWorker project path check case insensitive

[sebasgomez238]

What are you trying to accomplish?

Make file check in DiscoveryWorker case insensitive. This allows projects referenced from solution files to be found even if the case of the file path is different.

Currently we have issues where a .sln file references a project found on disk but we fail to discover it because the casing is different.

Fixes #10957

Anything you want to highlight for special attention from reviewers?

The approach taken was to crawl our way through the directories while and looking for matching names on each section while ignoring casing differences.

How will you know you've accomplished your goal?
