 * Executes the given Power Shell command or a whole script based on the
 * given options. Either of these options must be provided. If both are provided
 * then the `command` one gets the priority.
 * Note that Power Shell command cannot contain line breaks. Consider making it
 * to a script in such case.
 * Note that by default Power Shell blocks scripts execution, so the script must
 * temporarily switch user execution policy if necessary and restore it afterwards.
 * This makes scripts slightly less performant, as single commands.
 *
 * @returns The stdout of the given command or script
 * @throws If the exit code of the given command or script is not zero (stderr is used as the message when present).
