For the iOS SDK, we're going to create the dylib using our own logic, because our own logic supports executing remotely on a Mac.

Pull request overview
This pull request introduces the ability to opt out of creating a dylib (shared library) from Ready-to-Run (R2R) output for iOS SDK scenarios. The change allows the iOS SDK to use its own logic for dylib creation, particularly to support executing remotely on a Mac.
Changes:
- Added a new MSBuild property
PublishReadyToRunCreateSharedLibraryto control dylib creation - Modified the
_LinkReadyToRunMachOtarget condition to respect this opt-out property

I think this looks good. The error experience will be a little funky if someone sets this property without using the iOS SDK, but I think that's fine.
