NativeAOT: re-enable dead stripping

[rolfbjarne]

We've disabled passing -dead_strip to ld for NativeAOT:

• NativeAOT: Do not pass -dead_strip to the native linker #18552
• Do not include -dead_strip when native linking a NativeAOT object file #18553

It should be re-enabled once this is fixed:

• NativeAOT produces static library that makes ld crash runtime#88032

Once dotnet/runtime@d9a6607 flows in, we should try enable -dead_strip by default with NativeAOT.

Is xamarin-macios still using ld_classic? then I assume it'd still be affected by dotnet/runtime#88032

Yes ld_classic is still used (this will have to be fixed as the option is getting removed by Apple in XCode 16).

dotnet/runtime#88032 reported an issue that occasionally monotouch-test crashes the platform linker. However, at that time object file produced by NativeAOT was not marking all symbols as non-strippable.

The idea is to try turning -dead_strip back on and track if it is going to cause any failures.
