Deeper MSBuild logging integration

**Is your feature request related to a problem? Please describe.**

After https://github.com/ionide/FSharp.Analyzers.SDK/pull/241 goes in, it would probably make sense to ship our own MsBuild Task implementation so we can output correct message levels to MsBuild itself.

**Describe the solution you'd like**

Some mapping layer from our `ILogger` to MsBuild's Events: https://learn.microsoft.com/en-us/visualstudio/msbuild/task-writing?view=vs-2022#raise-events-from-a-task

**Describe alternatives you've considered**

Not doing it.
