Allow specifying environment variables in Exec Task

See original GitHub issue

The Exec Task currently doesn’t allow specifying environment variables which would be set for the to invoked process.

Example use case

The SDK currently defines a Run target which is used by VS to F5 an application. The properties used in the Run target are RunCommand, RunArguments and RunWorkingDirectory: https://github.com/dotnet/sdk/blob/3ed908ee77c592bae787ac78f466c3bc0581970a/src/Tasks/Microsoft.NET.Build.Tasks/targets/Microsoft.NET.Sdk.targets#L757.

If the Exec Task would allow specifying environment variables we could add a RunEnvironmentVariables property which would remove the need for an extra launchSettings.json file: https://github.com/dotnet/runtime/blob/817ebcaeb617813f98650e78c14e76bbd8b733b0/eng/testing/launchSettings.json#L14-L16.

Exec does support this.

Example from the Mac I’m on right now:

<Project>
  <Target Name="Exec">
    <Exec Command="env | grep FOO"
          EnvironmentVariables="FOO=bar" />
  </Target>
</Project>

$ echo $FOO


$ dotnet msbuild exec-env.proj
Microsoft (R) Build Engine version 16.5.0+d4cbfca49 for .NET Core

  FOO=bar

@ghogen, I suspect this is an example of the ToolTask-derived task docs not being sufficiently clear that they expose the ToolTask parameters. We have a link in each of them pointing to the base class, but is there a way to define a central snippet that could be included in each doc page?
