Haiku: Mark unsupported advanced network functions

[trungnt2910]

Add the UnsupportedOSPlatformAttribute for Haiku to managed network functions in System.Net.NetworkInformation to provide a consistent API on Haiku.

Part of #55803.

This one should be quite simple.

We should also want the attributes in ref source https://github.com/dotnet/runtime/blob/main/src/libraries/System.Net.NetworkInformation/ref/System.Net.NetworkInformation.cs , which matches illumos and solaris.

Pull request overview

This PR adds UnsupportedOSPlatform("haiku") attributes to network functions in System.Net.NetworkInformation that are not supported on the Haiku operating system, providing compile-time warnings to developers using these APIs on Haiku.

• Adds Haiku platform annotations to match existing illumos/solaris unsupported APIs
• Ensures consistent platform API surface across Unix-like operating systems
• Part of broader effort to properly support Haiku platform (issue #55803)

@trungnt2910, I think it is ok to bypass the network info API for the time being, but please note that illumos has two/three arch-dependent libs left to port and NetworkInformation is one of them. Generally, it's better to follow FreeBSD's lead as it's more complete surface area when deciding what's ok to "skip" in the built SDK/shared framework.

@am11 I am not blindly following illumos, at least in 2023 when I was porting the managed libraries. I tried to implement as many APIs relevant to Haiku as possible.

Haiku does not have the same kind of magic socket/socket options that Linux and FreeBSD have to fit into the current implementations in System.Native.

I made an attempt to squish what Haiku offers into the current codebase for NetworkInformation a while ago, but it didn't go quite well. To support this we will need some significant Haiku-specific implementations across System.Native and the managed libraries.
