[ios] HelloiOS - Set RunAOTCompilation only on Mono

[davidnguyen-tech]

Description

When we have /p:RunAOTCompilation=true and /p:UseMonoRuntime=false, dotnet publish fails with an ILStrip error because it routes the CoreCLR build through Mono's AOT-related targets that produce an empty assemblies list for ILStrip.

Because of that, we fix the HelloiOS sample to default to /p:RunAOTCompilation=true only on Mono.

Pull request overview

This PR restores the /p:RunAOTCompilation=false flag to the HelloiOS sample build and publish commands in the CoreCLR iOS documentation. The flag was inadvertently removed in PR #124230 but is necessary to prevent build failures when using CoreCLR on iOS.

Changes:

• Added /p:RunAOTCompilation=false to the dotnet.sh build command for the HelloiOS sample
• Added /p:RunAOTCompilation=false to the dotnet.sh publish command for the HelloiOS sample

Thanks. I suggest to add condition to the sample project instead:

<RunAOTCompilation Condition="'$(RunAOTCompilation)' == '' and '$(UseMonoRuntime)' == 'true'">true</RunAOTCompilation>
