"dotnet restore" and "dotnet publish" use relative BaseIntermediateOutputPath even if it's set to absolute path

### Describe the bug
"dotnet restore" and "dotnet publish" use relative `BaseIntermediateOutputPath` even if it's set to absolute path (or `$(SolutionDir)` gets lost in the process somewhere).
It's possible that `--artifacts-path` is ignored as well. I have tried setting it explicitly, as well as `/p:ArtifactsPath` and `...` in `Directory.Build.props`, but same result.

### To Reproduce

1. Create an empty solution
2. Add a .NET 8 GUI app project to it (into a subdirectory, i.e. `src//`)
3. Add a Directory.Build.props to the root solution directory with the following contents:
```xml

1701;1702;2087;2091
false
en-US
false
false
$(SolutionDir)build\intermediate\$(MSBuildProjectName)\
$(SolutionDir)build\staging\bin\$(MSBuildProjectName)\$(Configuration)-$(Platform)\

```
4. Add this to the .csproj of the created project:
```xml

WinExe
true

false
win-x64
true
true
true
true
true
false
false

false
true
true

```
5. Run project build via Visual Studio
6. The intermediate files (and directories) will be created in the project directory and not in `BaseIntermediateOutputPath` (`$(SolutionDir)build\intermediate\$(MSBuildProjectName)\`), though the hirerarchy will match except for `$(SolutionDir)` (almost as if it's ignored/evaluated to "")
7. The `dotnet publish` command will later fail with `Root assembly 'build\intermediate\\\.dll' could not be found`

### Exceptions (if any)

Not exceptions, but errors during publishing (see build log below).
