Make MultiSelect.value any[] instead of (string|number)[]

[ttrias]

Describe the bug

Currently, the value property of a MultiSelect object is defined as a (string|number)[]. However, SelectOptionType<any> allows the selected values to be complex objects. I am wrapping MultiSelect with a generic component, and I get an error trying to bind value to a T[]. Note that Select.value is of type any, so the binding there isn't problematic.

Note that this error isn't a showstopper, since it doesn't actually cause a build error; it just looks ugly in the IDE.

From Rider:

Types of property value are incompatible.
Type T[] is not assignable to type (string | number)[]
Type T is not assignable to type string | number

Reproduction

The lib\Test component uses the MultiSelect component with a T[]. Everything works, but Rider and VS Code both show a TypeScript error because T[] and (string|number)[] are not compatible.
