After git clone flutter/flutter, flutter commands require the use of
powershell to run ps1 scripts. On my corporate workstation, I need to
use a pwsh.bat wrapper to run ps1 scripts.

This PR uses `pwsh` instead of `pwsh.exe` to find and use a bat wrapper
from the path if present.

Closes flutter#171777.
