  tgrid::request_reduce_*: remove misleading code

These functions operate by calling twidget::request_reduce_* functions for
child widgets and not by changing values in column_width_ and row_height_.
Now when they no longer do the latter at all, and I added a comment to
clarify how the code works, hopefully understanding the code will be easier
for future developers.
