Feat(medusa, medusa-js, medusa-react): order edit item update (#2246)

**what**
Support `updateLineItem` which does the following:
- If no item change exist then create a new one and attaches the clone item with the adjustments and tax lines
- if an item change exists then delete/create adjustments and tax lines and update the cloned item quantity

**Tests**
- Unit tests core + client
- integration tests
  - When no item change already exists
  - When an item change already exists

FIXES CORE-497
