[main] Update dependencies from dotnet/arcade mono/linker

While looking at doing the conversion in dotnet/runtime after #7184 I noticed that having the reason argument reads weird, it's better to have the platform as the first argument so it reads more like a sentence.

E.g. instead of

```csharp
[SkipOnPlatform("System.Net.Security is not supported on this platform.", TestPlatforms.Browser)]
```

we have

```csharp
[SkipOnPlatform(TestPlatforms.Browser, "System.Net.Security is not supported on this platform.")]
```

Also allow multiple attributes since the skip reason can be quite different between platforms.

- Add emsdk (flows to aspnetcore)
- Remove extensions (no longer active in main)

Stable builds were not sending the aka.ms link prefix. I think this is safe, now that all the blobs are unique, and typically these are internal anyway.
Also, combine NonStableInternalFeeds and NonStablePublicFeeds into one method, as they were basically identical, aside from one tweak around symbols
