[PATCH 1/3] perf scripts python: exported-sql-viewer.py: Fix copy to clipboard from Top Calls by elapsed Time report

[Adrian Hunter]

Provide missing argument to prevent following error when copying a
selection to the clipboard:

Traceback (most recent call last):
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 4041, in <lambda>
    menu.addAction(CreateAction("&Copy selection", "Copy to clipboard", lambda: CopyCellsToClipboardHdr(self.view), self.view))
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 4021, in CopyCellsToClipboardHdr
    CopyCellsToClipboard(view, False, True)
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 4018, in CopyCellsToClipboard
    view.CopyCellsToClipboard(view, as_csv, with_hdr)
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 3871, in CopyTableCellsToClipboard
    val = model.headerData(col, Qt.Horizontal)
TypeError: headerData() missing 1 required positional argument: 'role'
