[Feature]: Add `multiselectDelimiter` property to `Combobox` and `Dropdown`

[leduyquang753]

Library

React Components / v9 (@fluentui/react-components)

Describe the feature that you would like added

Currently the delimiter of the displayed values of Combobox and Dropdown is hardcoded to be , . This appears to be a regression from v8 where there was a multiSelectDelimiter property. Thus, v9 should add back a similar property to these components.
