Determine if we should offer or deprecate focusTrapDisabled prop for input-date-picker and input-time-picker

[Elijbet]

Background

This is a follow-up issue to serve as a reminder that we need to determine next steps for input-date-picker and input-time-picker with regards to offering the ability to disable focusTrap.

input-date-picker / input-time-picker currently offers focusTrapDisabled and it could make sense depending on what the user is implementing in their workflows.

One suggestion is (@driskull) to deprecate focusTrapDisabled at some point in the future and have these components no longer support any focus trapping. They should act like a single component and be controlled via arrow keys only so tabbing past them is easier for an end user.

We need to collect feedback from teams from now until 4.x to helps us make a better call.

Desired Outcome

Determine if we should offer or deprecate focusTrapDisabled prop for input-date-picker and input-time-picker.
