Add support for annotated when defining fields

Summary by Sourcery

Enable support for using Annotated to define GraphQL fields by decoupling StrawberryField from dataclasses.Field and converting them into real dataclass fields during type wrapping.

New Features:

• Add StrawberryDataclassField for converting StrawberryField instances into dataclasses.Field representations
• Introduce _convert_field_annotations_to_dataclass_fields to process annotated fields on object types

Enhancements:

• Refactor StrawberryField to no longer subclass dataclasses.Field and store default, default_factory, and metadata directly
• Integrate annotated field conversion into the object type wrapping workflow
• Remove redundant type ignore comments and simplify generic checks in typing and info modules

Reviewer's Guide

This PR refactors how StrawberryField integrates with Python dataclasses by decoupling it from dataclasses.Field, introduces a dedicated StrawberryDataclassField wrapper with conversion logic, injects an automated conversion step for annotated fields in object types, and cleans up minor typings and utility functions.
