Bug 546935 - [Win32] Table: massive flickering packing columns by user

The problem manifested when:
1) `SWT.Measure` is connected (otherwise, `Table.wmNotifyHeader()`
   doesn't call `TableColumn.pack()` and Windows default code runs
   instead.
2) Column's header is wider than all items in the column.

This happened because `TableColumn.pack()` resized column twice: first
to item's width, then to header width.

The fix is to calculate the size and resize once.
