CustomSelect: Add WordPressComponentsProps

[brookewp]

What?

Part of #55023

Adding WordPressComponentProps for more flexibility in adding props.

Why?

To be able to add HTML attributes to CustomSelect and CustomSelectItem, the child items of CustomSelect. This will also be useful when adapting this to the legacy version.

How?

Adding WordPressComponentProps to inherit html attributes from a div element

Testing Instructions

1. Add a valid html attribute for a button to CustomSelect i.e. onBlur
2. Add a valid html attribute for a div to a CustomSelectItem i.e. className
3. Check there are no type errors and that it renders as expected

I initially thought of just adding to the child CustomSelectItem - however, the legacy CustomSelectControl can include
event handler props so I think that makes sense here too, but as a button rather than a div.

Good to be merged after adding a CHANGELOG entry 🚀
