Update theStart-NativeExecution cmdlet that is part of the build infrastructure to report the directory in which the script block was executed, in the event of an error.

PR Context

I ranStart-PSBuild, and it failed with an error during the ResGen phase:

PS /code/PowerShell> Start-PSBuild                                  VERBOSE: Using default feeds which are Microsoft, use -UseNuGetOrg to switch to Public feedsWARNING: The 'dotnet' in the current path can't find SDK version 10.0.100, prepending /home/logiclrd/.dotnet to PATH.VERBOSE: In Find-DotNetVERBOSE: Executing:  dotnet --list-sdks VERBOSE: Find-DotNet: dotnetCLIInstalledVersion = 10.0.100; chosenDotNetVersion = 10.0.100VERBOSE: Using configuration 'Debug'VERBOSE: Using framework 'net10.0'VERBOSE: Using runtime 'linux-x64'VERBOSE: Top project directory is /code/PowerShell/src/powershell-unix=== BEGIN: Restore NuGet Packages ======= END: Restore NuGet Packages ====Run ResGen (generating C# bindings for resx files)The build failed.

This error message told mewhat went wrong:dotnet run

It told me in general terms what was happening when it went wrong:Run ResGen

But this information alone wasn't enough to diagnose the problem.dotnet run in the root obviously doesn't do anything and isn't connected with the error at all. I had to open upbuild.psm1 and find out what exactly was on line 2666:

function Start-ResGen{    [CmdletBinding()]    param()    # Add .NET CLI tools to PATH    Find-Dotnet    Push-Location "$PSScriptRoot/src/ResGen"    try {        Start-NativeExecution { dotnet run } | Write-Verbose    } finally {        Pop-Location    }}

Ahh. It's doing it inside./src/ResGen.

So, this PR updates the error message so that obtaining this context doesn't require peeking intobuild.psm1 directly:

Exception: /code/PowerShell/tools/buildCommon/startNativeExecution.ps1:42Line |  42 |                  throw $errorMessage     |                  ~~~~~~~~~~~~~~~~~~~     | Execution of { dotnet run } in '/code/PowerShell/src/ResGen' by build.psm1: line 2666 failed with exit code 1
