Investigate/implement `__LINKEDIT` size reduction

[rolfbjarne]

See dotnet/runtime#86707 for background information.

Basically we want to look into whether we can produce smaller binaries by passing the exported functions to the native linker (as opposed to stripping them away later).

The referenced issue only talks about this in the context of NativeAOT, but this might benefit us on all platforms, not just NativeAOT.

This was also noticed with Mono (to much smaller extent), where the __LINKEDIT Export Info takes up 238360 bytes of zeros with MAUI iOS template app: https://gist.github.com/ivanpovazan/97ec573836caca3f8347b8eafa2cad14
