Allow launching of local files in Internet Explorer mode

This policy controls the availability of the --ie-mode-file-url command line argument used to launch Microsoft Edge with a local file specified on the command line into Internet Explorer mode. This setting works in conjunction with 'InternetExplorerIntegrationLevel' (Configure Internet Explorer integration) (which is set to 'IEMode'). If this policy is set to "true", or don't configure it, the user is allowed to use the --ie-mode-file-url command line argument for launching local files in Internet Explorer mode. If this policy is set to "false", the user isn't allowed to use the --ie-mode-file-url command line argument for launching local files in Internet Explorer mode.
