Fixes #3399
Previously the symbol showing two lines on the GridSplitter was being exposed to the UI Automation Tree with a value outside the valid unicode range.
This removes the textblock containing the symbol from the UIA tree as it's not needed. The whole GridSplitter shows up in the tree. The symbol is just a nice visual extra on the control.
