NativeAOT branches are publishing runtime.*.native.System.IO.Ports packages

[safern]

The NativeAOT branches are publishing runtime.*.native.System.IO.Ports packages and the prerelease label is the same as dotnet/runtime master branch, so this is causing race conditions in between dotnet/runtime official builds and dotnet/runtimelab builds in these branches. Because of the way we calculate version suffixes which contain a prerelease label, the date and an iteration version, that iteration is based on the build number of the day for the producing pipeline. Since we have two different pipelines that produce the same asset and have the same prerelease label in Versions.props as dotnet/runtime, we can get clashing assets in our symbol blob storages.

@MattGal do we know if it is possible to create blob storages per DARC channel since dotnet/runtime and dotnet/runtimelab publish to different channels?

This could happen again if a new experiment doesn't disable packages from building from that branch and just produce the packages they need and don't update the prerelease label. We need to add an entry for the packages bits in the create experiment docs.

I don't think we should update the label for the NativeAOT experiments as they are supposed to just produce the ILCompiler package and this is the only source of that package.

@safern The issue seems resolved, should we close it?

[safern]

Yup. Thanks!
