Add deprecation warning to GetTextSize API

Adds a runtime warning to `Engine.GetTextSize` indicating that the API
is deprecated and will be removed in a future version.

This API does not simulate GUI rendering accurately, as it treats markup
tags like [color], [font], or [icon] as visible characters. This leads
to incorrect size measurements in modern GUI layouts.

New recommended alternatives:
- Use `Engine.GetGUITextSize(...)` for accurate measurement of raw text
  blocks, fully simulating GUI rendering.
- Use `guiObject.getTextSize()` when working within a specific GUI
  object, as it accounts for maxWidth, padding (bufferZone), and object
  constraints.

A warning is now emitted at runtime to guide developers toward these
updated APIs.
