[NTOS:CM] Allow CmSelfHeal to be configured via registry.

This is controlled with a REG_DWORD value named
`SelfHealingEnabled` inside the registry key
`HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Configuration Manager` .

The `CmSelfHeal` variable is used to retrieve the data,
hence it needs to be a ULONG.
