As suggested by @KoBeWi, this PR is separated from #98335. It closes godotengine/godot-proposals#2727 by allowing one variable definition as condition in if-statement (e.g.
if var n := foo():).For discussion of a new syntax for mixing multiple variable definitions and expressions in a single if-statement (e.g.
if var n := foo(), n > 100:), please refer to #98335.
