[Video Sequence Editor] Feature request: option to center align text

As of issue #131068 , it was suggested to have the option to center-align, right-align, left align or justify text on the Video Sequence Editor. Currently, it will always left-align.

Even though we have an Anchor X option, it only changes the anchor for the whole text object (as it should). The suggestion is to have an additional option in the style panel that allows us to choose how we want the text alignment to be. Ideally we should also be able to do vertical text (as in each letter be stacked on top of the others).
