Allows you to add your own custom shadow argument reporters. (reporters that duplicate when they are shadowed and dragged)

Test Coverage

No tests, this is very simple

I think it would be better to have this as a property on the block, and then register an extension (like shadow_argument_reporter) that sets that property. Then it could be put into the extensions property, but oh wait that might not work in cases where the extension does not exists so uh

eh, that would require deeper changes and its only used by this check

it is better for this to be set declaratively on the block in getInfo() then the vm will forward it along
