[FIX] Fix dotted path instantiation and resolving. and support generic type when instanting

[ahmed7p]

This PR fixes dotted path instantiation and resolving, and adds support for generic types when instantiating.

Changed

• Generic Type Parsing: Updates the parser to support type parameters within new expressions (e.g., new StringMap<Class<Dynamic>>()).
• Dotted Path Instantiation: Adds fallback resolution via dotted paths in cnew for classes, abstracts, and static references.
• Class & Package Reference: Fixes field access and resolution so accessing base class or package references directly (e.g., flixel.FlxG without a trailing field) no longer throws errors.

Example

// 1. Dotted path instantiation (Now works without explicit imports)
var spr = new flixel.FlxSprite();

// 2. Standalone dotted path resolution (No longer throws without trailing fields)
var core = flixel.FlxG;

// 3. Generic types in instantiation (Now safely parses without errors)
var myMap = new StringMap<Class<Dynamic>>();

StringMap<String, ...>? It only accepts one type parameter.
