vi: Unify resolutions values and accurate implementation of them. (#2640)

* vi: Unify resolutions values and accurate implementation of them.

To continue what was made in #2618, I've REd `vi` service a bit. Now values and checks related to displays are more accurate.

- `am`  GetDefaultDisplayResolution / GetDefaultDisplayResolutionChangeEvent have more informations on what the service does.
- `vi:u/vi:m/vi:s` GetDisplayService are now accurate.
- `IApplicationDisplay` GetRelayService, GetSystemDisplayService, GetManagerDisplayService, GetIndirectDisplayTransactionService, ListDisplays, OpenDisplay, OpenDefaultDisplay, CloseDisplay, GetDisplayResolution are now properly implemented.
- Some other calls are cleaned or have extra checks accordingly to RE.

Additionnaly, `IFriendService` have some wrong aligned things, and `pm:info` service placeholder was missing.

* just use _openedDisplayInfo.Remove()

* use context.Memory.Fill()

* fix some casting

* remove unneeded comment

* cleanup

* uses TryAdd

* displayId > ulong

* GetDisplayResolution > ulong

* UL
