Partially Fixes #2483 - Removes old Border and leverages LineCanvas for Frames, etc... (#2527)

* POC

* View.DrawFrame now uses LineCanvas

* Fixes #2531. Toplevel should redraw only if it's needed.

* Fix toplevel when mdi is enabled preventing clear the screen twice.

* Massive LineCanvis updates

* Fixes #2534. Bounds isn't updating when the Frame is changed.

* Almost everything works!

* Had to disable a few tests but all unit test now pass again

* Deleted ConsoleDriver.DrawWindowFrame; hacked ProgressBar

* Deleted ConsoleDriver.DrawWindowTitle; moved to Frame.DrawTitle

* Renames BorderFrame to Border

* Removed old commented code

* Tweaked scenario

* Added auto convert \r\n to Enviornment.NewLine in TestHelpers.AssertEqual

* Fix merge errors.

* Fix AssertEqual newlines to platform-specific.

* Refactored frames drawing; view adds to its lineview, superview renders them

* New titlebar style based on Border.Top size; fixed bugs

* wzard bug
