Backport of #113313 to release/9.0-staging

/cc @matouskozak

Currently, we are using osx.1200.amd64.open and osx.1200.arm64.open for dotnet/runtime Apple simulator and MacCatalyst jobs. Since macOS 12 is after its EOL, we should migrate to queues with newer macOS version.

iOSSimulator, tvOSSimulator, MacCatalyst pipelines are migrated to:

• osx.15.amd64.open
• osx.14.arm64.open (until osx.15.arm64.open has enough machines)

Disabling failing tests against tracking issues.

• The PR target branch is release/X.0-staging, not release/X.0.

Package authoring no longer needed in .NET 9

IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older versions.
