Preserve automatic Popover visibility when enabled.

When popoverProps supplies isVisible: null, ?? popoverOpen replaces null with a boolean. In packages/react-core/src/components/Popover/Popover.tsx, Lines 229-388, null selects automatic visibility; a boolean selects manual visibility.

For example, with popoverProps={{ isVisible: null, triggerAction: 'hover' }}, hovering previously opened the calendar. It now calls the default no-op shouldOpen, so the calendar does not open.

Force false while disabled, but preserve an explicitly supplied isVisible value when enabled.

Review comment at @packages/react-core/src/components/DatePicker/DatePicker.tsx at line 320:
Update the DatePicker Popover isVisible prop so disabled state always forces false, while enabled state preserves an explicitly supplied popoverProps.isVisible value, including null, and otherwise uses popoverOpen.
