QQuickTableView: change the order of row and column to modelIndex()

In Qt 6.3, TreeView had a function called modelIndex().
This function took two arguments: row and column.
In Qt 6.4, This function was moved into TableView
(the superclass) instead, since it was needed in both classes.
And in that process (probably because this was done
in several patches), the order of the arguments got
swapped, to conform with two other functions in
TableView that took a column and row as argument.

But this was a source incompatible change.

The result is that TreeView in Qt 6.3 has a function
modelIndex(row, column) that works differently compared
to Qt 6.4.0. The signature there is modelIndex(column, row).

This patch will therefore effectively revert that
SiC, and let modelIndex() again take row and column as
arguments, like in Qt 6.3.

The downside is that we already have two versions
of Qt released (6.4.0 and 6.4.1) that contains the SiC.
We therefore offer an environment variable that
can be set to use the swapped version, if needed.

[ChangeLog][Quick][TreeView] Because of a source incompatible
change in Qt 6.4.0 and Qt 6.4.1, modelIndex(column, row) has
been reverted back to modelIndex(row, column), equal to how it
was in Qt 6.3. This also affects modelIndex() in TableView.
If the order used in Qt 6.4.1 is needed, you can set the
environment variable QT_QUICK_TABLEVIEW_COMPAT_VERSION=6.4

Pick-to: 6.5 6.4 6.4.2
