Support launching net taskhost - initial implementation

[YuliiaKovalova]

Partially Fixes https://github.com/dotnet/msbuild/issues/11331

To test the feature, setup these env variables: MSBuildToolsDirectoryNET = e.g. "C:\msbuild\msbuild_yk\msbuild\artifacts\bin\bootstrap\core" MSBuildAssemblyDirectory = e.g. "C:\msbuild\msbuild_yk\msbuild\artifacts\bin\bootstrap\core\sdk\9.0.203"

Keep in mind, due to current handshake mechanism, only matching (or adjusted with this change) version of sdk can be launched.
