HelloiOS sample for NativeAOT

[ivanpovazan]

Description

• HelloiOS sample application used for monitoring size and performance regressions on iOS platforms is currently used only with Mono.
• Once AppleAppBuilder support is implemented, adapt the sample or create a new application which would serve the same purpose for NativeAOT.

Proposal

The sample app would be used to prove that:

• First step - NativeAOT can build and run a PoC iOS application with native UI and managed interop (on both: simulator and device) Adding HelloiOS sample for NativeAOT #82249
• Second step - Full integration with dotnet SDK and internal build tasks for targeting iOS platforms (integrate System.Globalization.Native and support all iOS-like platforms)

@ivanpovazan fyi I've started integrating the sample app as a functional test on the CI. Full integration with dotnet SDK and internal build tasks for targeting iOS platforms shouldn't change the CI as it uses make script.
