DevTools: Add "Copy as PowerShell" option for network requests

PowerShell is a powerful command-line shell which is preinstalled on all
Windows 7+ machines and is capable of issuing arbitrary network
requests. This change adds two options to the network request context
menu on Windows systems: "Copy as PowerShell" and "Copy all as
PowerShell".

Testing done: strings from the old curl-command.html and the Big List of
Naughty Strings (https://github.com/minimaxir/big-list-of-naughty-strings)
were submitted as request URL and bodies. Requests then were copied,
submitted from PowerShell and cURL (bash) and compared on the server side.
All requests got byte-for-byte match.
