Refactor tile_window.hpp, tile_window_linear.hpp into a CK Tile Hierarchy (#2214)

Browse Source 
* window_origin variable now in base class

* abstracted more functions

* consolidated tile_window_static_distribution and tile_window_static_lengths

* clang format

* skeleton code for tile_window and tile_window_linear consolidation

* more abstraction

* moved variables from child to parent

* clang format

* removed comments

* removed debug code

* removed debug code

* abstracting traits WIP

* consolidated traits

* removed comments and clang formatted
