Pull Request Overview

This PR fixes the PublishReadyToRunEmitSymbols property initialization to respect user-provided values. Previously, the property was unconditionally set to false for Apple platforms (iOS, tvOS, macOS Catalyst), which prevented users from overriding this behavior.

Key Changes:

• Modified the condition for PublishReadyToRunEmitSymbols to only set it to false when the property hasn't been explicitly set by the user

I think arcade overrides PublishReadyToRunEmitSymbols in https://github.com/dotnet/arcade/blob/7d717a49d570577936361c14de38bf61271aa274/src/Microsoft.DotNet.SharedFramework.Sdk/targets/sharedfx.targets#L10

iOS build is failing with the System.NotImplementedException: iOS

[jkoritzinsky]

We can change arcade to not forcibly override it.
