QConcatenateTablesProxyModel: skip dataChanged in hidden columns
When the source models don't have the same number of columns, the proxy
keeps only the smallest number of columns across all source models.
Afterwards, if a source model emits dataChanged in a column past
that number (a "hidden" column), the proxy needs to ignore it rather than
assert.
But also, if the source model emits a dataChanged signal across both
visible and hidden columns, then the last column number needs to be
adjusted so that the signal is correctly processed and forwarded.
Task-number: QTBUG-91253
Pick-to: 6.1 6.0 5.15
