Enhancement: combobox invalid prop and status

[sam11927]

Description

Combobox should have an invalid state (add a status prop)

Acceptance Criteria

Combobox shows red border and can accept an input-message as well.

Which Component

calcite-combobox

Example Use Case

want to show that the combobox is a required field, so when someone clicks in and doesn't select something, set the status to invalid and display an error message (in the form of an input-message).

@sam11927 do you still have a need for this invalid state on Combobox?

The input-message can be placed adjacent to the Combobox itself like this: https://codepen.io/mac_and_cheese/pen/bGxQEMv?editors=1000

Rescoped to fit the combobox's invalid status and include a prop.
