Remove assert_in_view parameter to TextMetrics::editXY

This parameter was not used anymore since commit 9c443d96. The
description of that commit said

"Use assert_in_view = false when calling TextMetrics::editXY() because
 this parameter does not work as advertised: if an inset not totally
 visible, the code will not try to go inside it to look for a smaller
 row that is totally visible."

Rename accordingly getPitAndRowNearY to getRowNearY.
