[ROSLOAD]: Continue work on target preparation OslPrepareTarget 2/104.

[ROSLOAD]: Stubplement OslpCheckForcedFailure, OslpGetSetBootStatusData, OslSetBootStatusData, OslGetBootStatusData.
[ROSLOAD]: Stub OslpInitializeBootStatusDataLog, OslpReadWriteBootStatusData.
[BOOTLIB]: Fix BlAppendBootOptionString to accept an actual BCD ID instead of hardcoding LibraryPath.
[BOOTLIB]: Fix BlAppendBootOptionBoolean to accept an actual BOOLEAN value instead of hardcoding TRUE.
[BOOTLIB]: Implement BlDeviceIsVirtualPartitionDevice.
[BOOTLIB]: Add missing BcdOSLoaderInteger_ForceFailure BCD value. Add BCDE_OSLOADER_TYPE_BOOT_STATUS_POLICY based on BcdEdit.exe and Geoff Chappel site.
