Build output of OutputType Exe is transitively copied even if ReferenceOutputAssembly False

### Issue Description
Build output of OutputType Exe is transitively copied even if ReferenceOutputAssembly False.

### Steps to Reproduce
A.csproj
```
Exe
```

B.csproj
```

False

```

C.csproj
```

```

Run `dotnet build C`

### Expected Behavior
There is no `A.exe` in output the dir of B or C

### Actual Behavior
There are `A.{exe,deps.json,runtimeconfig.json,runtimeconfig.dev.json}` in the output dir of B or C

`MSBuildCopyContentTransitively = False` helps to some extent. It removes other files except the exe.

PrivateAssets all, IncludeAssets none, ExcludeAssets all doesn't help.
