Don't use row/column headers for selection incompatible with mode

Mouse events in row/column headers should be just ignored when the
current selection mode disallows row/column selection.

This wasn't the case before, and while actually selecting the line
corresponding to the header was disallowed further down the call chain,
clicking it still unexpectedly cleared the existing selection and
dragging mouse in the header window selected the entire grid.

Fix this by just never entering the corresponding cursor mode in the
first place if it's incompatible with the current selection mode.
