Revert e2e7d3d391 (Fix wxELLIPSIZE_END with wxALIGN_RIGHT in wxMSW
wxDataViewCtrl, 2016-03-18). This fix is no longer needed after
the previous commit reverted b642747fd2.
Reverting also allows for text to be drawn vertically aligned again
instead of always using top-left alignment. While the difference in
appearance by not having alignment can be minor with default row
heights, it becomes more noticeable with taller rows:
a wxDataViewCheckIconText column with a tall icon will have its text
stuck to the top of a row while other columns have their text vertically
centered. This already occurs by default when not explicitly specifying
an alignment (wxDVR_DEFAULT_ALIGNMENT) which results in
wxALIGN_CENTRE_VERTICAL being used for row alignment when rendering.
