Tables: four small fixes.

Fixed last item flags leaking to disabled column, affecting IsItemHovered(). (#3651).
Validate and fix invalid DisplayOrder data from ini file.
Allow TableHeaderRows() to function will missing TableSetupColumn() calls.
Made TableHeader() use AllowItemOverlap mode to allow submit subsequent item in same cell, since it covers the whole cell area.
