For more complex types such as V3D, the python API for TableWorkspace
used to return a incomprehensible string. Now it returns a proper
string type name.

So we no longer get this off the item. infoSize didn't make sense as part of the
public api for the items of the info iterators.

Input workspace history needs to be copied to output workspaces. In
the case of groups, where an output replaces an input, the input history
can disappear before we have time to copy it to the output.

The pointer to the last workspace should be declared before the for loop
otherwise it will always be a nullptr.

The test were performing a multiplication instead of addition/
subtraction.

Re #0

ConjoinXRuns should not care if the workspaces have same bins, only that
they look like blocks.

Re #24462

Also some improvements to detector info iterator. Note that I added an
index property. I see this as being particularly useful for users to get
away from the old instrument python API. i.e.

for item : component_info
    if item.index == component_info.source:
        break
