mach: New powershell script mach.ps1 mimicking globbing of Unix (#39730)

Unix terminal natively supports globbing, but Windows don't. That's why
command like `.\mach update-wpt D:\selenium_servo\linux\*.log` works
differently on Windows.

This PR creates a new script `mach.ps1`. 

1. If user uses cmd, `./mach` still runs `./mach.bat`.
2. If user uses powershell, `./mach` runs `./mach.ps1`, supporting the
feature mentioned.

Testing: Manually tested. 
Fixes: #39724
