Fixes the chat text to properly align to the bottom of the screen.
In the stock game the chat text (MP text messages, AI radio messages, etc.) appears to be misaligned on various aspect ratio and UI size settings.
This is down to lacking optimization for the newly introduced safe zone. The purpose of this fix is to introduce such optimization, hence making sure the chat always sticks to the bottom of the screen, no matter what aspect ratio or UI size you use.
