Support "ignore errors" type mode in native toolset installs

[chcosta]

winforms and wpf repos have a dependency on current behavior of native toolset bootstrapping which unintentionally ignores some failure.

The result is that we have to omit pipeline telemetry output for this part of our code or else we will force this to fail during CI builds. This creates a gap in our telemetry as we don't have insight into when native toolset bootstrapping is really causing problems in repos.

Not sure if this still needs to be done -- kicking to triage for further discussion.

In .NET 6+ dotnet/winforms moved the intellisense bundles from global.json; dotnet/wpf moved the intellisense bundle from global.json in .NET 7.

This work is not planned at this time, and we are removing how this code handles native assets, so we are closing this as not planned.
