Kernel/Storage: Migrate the partition code to use the ErrorOr container

Browse source 
That code used the old AK::Result container, which leads to overly
complicated initialization flow when trying to figure out the correct
partition table type. Instead, when using the ErrorOr container the code
is much simpler and more understandable.
