[libraries] Update System.Runtime.Extensions tests for iOS,MacCatalyst,tvOS (#57210)

* [libraries] Update AppDomainTests for iOS,MacCatalyst,tvOS

* Update skip reasons

* Add MacCatalyst to Case Insensitive and remove ActiveIssues

* Replace ActiveIssue with ConditionalTheory based on RemoteExecutor

* Fix test for iOS/tvOS/Catalyst

* Skip UserName test on iOS tvOS
