[dotnet-run] fix logging and Restore for device selection

c164a9b is mostly working with two issues I've discovered while testing:

1. If `ComputeAvailableDevices` requires `Restore` to have run (which
   is actually the case for iOS and Android), `dotnet run` would fail
   unless you did an explicit `dotnet restore` first:

    D:\src\helloandroid> D:\src\dotnet\sdk\artifacts\bin\redist\Debug\dotnet\dotnet.exe run -bl
      failed with 1 error(s) (0.1s)
      D:\src\dotnet\sdk\artifacts\bin\redist\Debug\dotnet\sdk\11.0.100-dev\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(266,5): error NETSDK1004: Assets file 'D:\src\helloandroid\obj\project.assets.json' not found. Run a NuGet package restore to generate this file.

We can test this by changing `DotnetRunDevices.csproj`:

    <Target Name="ComputeAvailableDevices" DependsOnTargets="ResolveFrameworkReferences">

Doing an explicit `Restore` step before `ComputeAvailableDevices`
resolves this.

2. We were not passing loggers `ProjectInstance.Build()` calls in
   `RunCommandSelector`, so no logging output was shown during device
   computation. This is now fixed by creating a fresh console logger
   each time we call `Build()`.

I tested this manually with a console app with a
`ComputeAvailableDevices` target and a lengthy sleep:

    helloconsole                 ComputeAvailableDevices (9.1s)
