First stage of moving InDet Errors to IDC ATR-20647

With the MR a new IDC like collection for InDet BS Errors is created next to the old one

The plan is as follows now:

• move clients to use the new collections
• move producers to directly produce this collection In a bit longer term we will optimise the memory management. A single integer is not best member of the IDC. This can be probably achieved using memory arenas that are already available. Alternative approach would be to modify IDC so that it can handle values.
