Migrate Figure.colorbar tests to use dvc (#1143)

* remove test_colorbar_using_paper_coordinates_horizontal()
* remove test_colorbar_box_with_rounded_corners()
* remove test_colorbar_shading_string()
* remove test_colorbar_positioned_using_justification_code()
* remove test_colorbar_box_with_secondary_border()
* remove test_colorbar_box_with_clearance()
* remove test_colorbar_box_with_pen()
* remove test_colorbar_box_with_offset_background()
* update test_colorbar_shading_boolean() to use mpl_image_compare
* remove test_color_shading_float and update test_colorbar_shading_list to use mpl_image_compare
* remove .png files, add .dvc files
* remove test_colorbar_positioned_using_normalized_coords()
* remove test_colorbar_positioned_using_map_coordinates()
* remove test_colorbar_using_paper_coordinates()
