Linux: Automatically increase vm.max_map_count if it's too low (#4702)

Browse source 
* memory: Check results of pinvoke calls

* Increase vm.max_map_count when running Ryujinx

* Add SupportedOSPlatform attribute for WindowsApiException

* Revert increasing vm.max_map_count via script

* Add LinuxHelper to detect and increase vm.max_map_count

With GUI dialogs, this should be a bit more user-friendly.

* Supply arguments as a list to RunPkExec

* Add error logging in case RunPkExec() fails

* Prevent Gtk from crashing
