RFR: 8295248: JEditorPane HTML form with multi-selection broke data after resetting [v4]

[Toshio Nakamura]

> When JEditorPane shown HTML form with multi-selection, the reset operation broke its data.
> 
> The sample testcase were attached in JBS. The recreate steps are below:
> 1. The sample shows a multi-selection form with 5 items.
> 2. Select the 4th item.
> 3. Press the reset button.
> Actual: The 4th item is still selected.
> Expect: No item should be selected. Resetting operation may move to the initial state. The sample doesn't use 'selected' property in each option tag.
> 4. Just after the step 3, move the focus to outside of the application and back.
> Actual: The 2nd item is selected. It means inside data indicates so.
> Expect: No item is selected.
> 
> There are two issues. The current method `OptionListModel.removeIndexInterval()` removed the indexed item, and shifted the rest. Then, selection values were corrupted.
> I think the clear selection method `OptionListModel.clearSelection()` is suitable here.
> 
> Test: jdk_desktop on macOS (x64, Monterey), Linux (x64, RHEL8), and Windows (x64, 2012R2).
>       No regression found
