[macro] Declaring typedef not working and ruins macro generation

[dsvishchov]

When trying to declare a simple typedef generation stops at typede when typing and ruins macros generation at a whole, so nothing works unless this statement is removed/commented out.

For example:
builder.declareType('Test', DeclarationCode.fromString('typedef Test = int;'));

Dart version: 3.6.0 (same behavior was on 3.5.3 as well)

Summary: typedef declaration within a macro using DeclarationCode.fromString fails in Dart 3.6.0 and 3.5.3, preventing subsequent macro generation. The issue occurs when using builder.declareType.
