This adds support for APMv3 I/O, menus and the launcher.
* Added a apm3hook dll and I/O based on the usual layout.
* Added C:\Mount\Apm to vfs.
* Added the relevant .dlls to unityhook.
* Added a hook for apmmount.dll that uses `CreateDosDevice` to mount decrypted data to the locations the launcher and games expect files to be. This will conflict with anything that is already at W:\ and X:\, but I do not have better solutions for this.
* `launch.bat` is a bit more involved as it simulates the launcher loop. It can be broken by alt+f4ing or closing the launcher with "X".
* An extra export was added, so rundll32 can be used to get rid of the dosdevices after the launcher was killed.
* Since all the games do everything via `X:\lib\apm.dll`, no game hooks were needed in testing, therefore, `game.bat` files can be used as is.
* Path hooks are applied correctly, so you can go correctly between games, launcher, sub system test mode and game test modes.
A setup guide (some stuff specific to my server) can be found here:

Tested with the 2 APM sample apps, Blazblue, Puyo, Guilty Gear and some weird unity puzzle game whose name I forgot.
