Limit PNSE by using Invariant HashCode in HybridGlobalization (#96354)
* Unblock all tests. * SortKey is Invariant now. * Missing SortKey changes + fix HashCode. * Typo * Revert unbocking tests connected with CompareOptions PNSE. * Hashing uses Invariant mode -these tests should be skipped. * Add active issue. * feedback * Feedback * Better documentation. * Add new tests + sanitize string before invariant comparison. * Comment + more cases. * Clean CI. * Missing change for clean CI commit. * `SortKey` not supported for non-invariant cultures, `HashCode` supported for non-invariant cultures only with `IgnoreCase` or `None` options. * Feedback. * Fix build, add docs. * Feedback @matouskozak @pavelsavara * Added tests + fixed algo. * Block failing tests for a follow-up PR. * Add more details to PNSE. * Feedback - correct comment
