This commit is needed for building a single bootcd registry hive. It will also enable 1-st stage setup to have a proper registry present as done on Windows.
CORE-13347
[CMAKE]
Note that the mkhive commands should really depend on the generated UTF16 INF files since the latter are those that are actually used as input for mkhive.
Otherwise, the mkhive calls & the UTF16 INF file conversion is not serialized and we can generate "corrupted" hives due to the fact that mkhive is using
INF files that are in the process of being (and therefore, only partially) generated.
