Hermès Bélusca-Maïto cc40a5870a
[NTOS:CM] Implement Win7+ VolatileBoot support. 
Its support is controlled with a REG_DWORD value named
`VolatileBoot` inside the registry key
`HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Configuration Manager` .

Its implementation is very trivial: when enabled, CmpShareSystemHives
is set to TRUE and doesn't change state during runtime.
In a sense this is similar to what happens in WinPE-boot, except that
ALL hives without exception (system hives and others) will be loaded
in shared mode.
