[SHELL32] Better determine whether to hide or show shell-folder namespace items (#9046)

Browse Source 
In `SHELL32_IsShellFolderNamespaceItemHidden()`, use `SHRegGetBoolUSValue()`
to look at both `HKEY_CURRENT_USER` with fallback to `HKEY_LOCAL_MACHINE`,
when searching for the registry value that determines whether a shell-folder
namespace item is to be hidden or shown.

Behaviour confirmed on Windows 2003.

Addendum to commit 6ae11ba09d (PR #7189).
