Setting `RunAOTCompilation=true` on non-wasm/non-mobile projects fails to build

[radical]

If a simple console project, for example, is built with RunAOTCompilation=true then it fails like:

/usr/local/share/dotnet/sdk/7.0.200-preview.22521.7/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.ImportWorkloads.targets(38,5):

error NETSDK1147: To build this project, the following workloads must be installed: macos [/private/tmp/c/c.csproj]
error NETSDK1147: To install these workloads, run the following command: dotnet workload restore [/private/tmp/c/c.csproj]

And this is because the MonoAOTCompiler.Task is imported with:
