Baseline alignment doesn't work on TextViews with fixed height

Baseline alignment doesn't work on TextView widget. We will work on it soon.

Ex: https://github.com/eclipsesource/tabris-js/issues/1272

Start with the TextView widget and the fixed-height baseline-alignment behavior described here, then read the linked issue #1272 for related context. Reproduce the example and determine the expected baseline position; done means baseline alignment works correctly for fixed-height TextViews.
