[PATCH 0/1] MR9041: msi: fix MsiEnumFeatures[AW]() by make it look at the correct registry

[Ratchanan Srirattanamet (＠ratchanan.sr)]

For some reason, MsiEnumFeaturesW() still look for the list of features
in the registry key which Wine itself has not been writing to since
commit af56e28f ("msi: Don't publish features to an invalid location."),
authored in 2008. Make it look in the new registry location which
is used by ACTION_PublishFeatures().

While we're at it, remove the helper function used only by
MsiEnumFeaturesW().

A conformance test is added.
