Fix generic wxDataViewToggleRenderer hit testing with any alignment.

This change reverts the changes of r73835 and r73838 to
wxDataViewToggleRenderer::WXActivateCell() and instead fix the bug with mouse
hit testing in this function in the wxDataViewMainWindow::OnMouse() itself.
The problem there was that it offset the coordinates of the event differently
depending on whether the column alignment was set or left as default. Now
always make the coordinates relative to the item (not cell) rectangle for
compatibility with GTK+ native version, which is enough to make the original,
i.e. before the changes of r73835, code work.

See #15144.
