[Feature Request]: MultiCombobox with loading prop

Feature Request Description

The current Combobox component includes a loading prop, which enables a loading indicator to signal a loading state. However, the MultiCombobox does not provide a similar API, resulting in inconsistent handling of the loading state across components. For improved developer experience and API consistency, the MultiCombobox should support the same loading prop.

Proposed Solution

• Add a loading prop to the MultiCombobox component, mirroring the behavior and API of the Combobox's loading state.
• Optionally, introduce a delay prop to control the BusyIndicator behavior, allowing for customizable delay times before showing the loading indicator.
• Expand support for the loading prop to the Select and MultiSelect components to ensure consistent loading state handling across all similar components in the library.

Proposed Alternatives

If aligning the API across components is not feasible or desired, consider removing the loading prop from the Combobox component to maintain consistency and avoid API discrepancies (with 3.0.0).

Start by comparing the existing Combobox loading API and behavior with MultiCombobox, then review how BusyIndicator delay is handled. Confirm whether the scope includes Select and MultiSelect, or only MultiCombobox, and define done as consistent loading support and documented behavior across the agreed components.
