RFR: 8282958: Rendering issues of borders, TextFields on Windows High-DPI systems

[Rajat Mahajan]

This fix is based on a similar approach as described here  https://github.com/openjdk/jdk/pull/7449#issuecomment-1068218648.
We rescale the line border to render the Textfield border correctly, so that all sides of the Textfield border are of same thickness.
