After JDK-8087673, the fix to take into account the width of the menu button applies to _all_ the TableColumnHeaders, while it should only be applied to the header of the last visible column.

TableHeaderRow::updateCornerPadding already mentions:

    // When the corner region is visible, and the vertical scrollbar is not,
    // in case the corner region is over the header of the last
    // visible column, if any, we have to consider its width as extra padding
    // for that header, to prevent the content of the latter from being partially
    // covered.

so the padding for the tableHeaderRow is calculated based on the last visible column:

padding = getRootHeader().getColumnHeaders().stream()
                    .filter(header -> header.isLastVisibleColumn)
...
cornerPadding.set(padding);

While this is correct, in TableColumnHeader::layoutChildren the width of _every_ header is calculated based on this padding:

        double cornerRegionPadding = tableHeaderRow == null ? 0.0 : tableHeaderRow.cornerPadding.get();
        double w = snapSizeX(getWidth()) - (snappedLeftInset() + snappedRightInset()) - cornerRegionPadding;

which is wrong for every header but the one from the last visible column.

In fact, the pics in the PR description (https://github.com/openjdk/jfx/pull/886#issue-1354147047) already show this issue, if one looks carefully:

- before.png: Before the fix, columns 5-8 headers have some padding to the left (expected), and column 9 is wrong (arrow is not visible).

- after.png: After the fix, headers of columns 5-8 have way less padding to the left (wrong!), and column 9 is fixed (arrow is visible).

This issue can be reproduced always since JavaFX 20 (and also since 17.0.7).
