Debugger: Fix sizing of debugger columns

Added span column property to BaseTreeView. This takes an index to a column
that will span remaining space not explicitly taken by the other columns.
This listens to resizing of the tree view and columns that are manually
resized to keep the sizes consistent.

The stack view now once again uses the StackView class, which now sets the
function column as the span column. This will adjust the column size the
first time stack frame contents are encountered. It will not resize
automatically until it's re-created (the next debug session) so it doesn't
undo custom resizing. This also restores the ability to toggle stack
addresses. Some obsolete parts of this class were removed as part of
retrofitting it for the current state of the debugger.

Stack, breakpoint, and thread views now resize remaining space for the
function column rather than empty space at the end. This is generally the
most important field when debugging and can get very long, especially in
C++.
