Laszlo Ersek c44501b313 ShellPkg: stop using EFI_HANDLE in place of EFI_HII_HANDLE
The UefiShell*CommandsLib instances have constructor functions that do
something like:

  gHiiHandle = HiiAddPackages (...);
  ...
  ShellCommandRegisterCommandName (..., gHiiHandle, ...);

and destructor functions that implement the following pattern:

  HiiRemovePackages (gHiiHandle);

The -- semantic, not functional -- problem is that "gHiiHandle" is
declared with type EFI_HANDLE, and not EFI_HII_HANDLE, in all of these
library instances, even though HiiAddPackages() correctly returns
EFI_HII_HANDLE, and HiiRemovePackages() takes EFI_HII_HANDLE.

Once we fix the type of "gHiiHandle", it causes sort of a butterfly
effect, because it is passed around widely. Track down and update all of
those locations.

The DynamicCommand lib instances use a similar pattern, so they are
affected too.

NOTE: in practice, this patch is a no-op, as both EFI_HII_HANDLE and
EFI_HANDLE are typedefs to (VOID*). However, we shouldn't use EFI_HANDLE
where semantically EFI_HII_HANDLE is passed around.
