* hle: Do not add disabled AoC item to the list
We currently add all AoC items to a list in `ContentManager` and the enable check is only done when FS service ask for the data. Which is wrong. It causes an issue in MK8D which doesn't boot even if you have disabled a not updated DLC.
I've fixed it by not adding the disabled AoC item to the list, I've removed some duplicate code too.
There is still an edge case because we currently don't check the AoC Item version, but that should be fixed later since now MK8D throw an error if the DLC isn't updated.
* remove useless "enabled"
