fix(core): NotRequired in TypedDict causes TypeError when converting to OpenAI function schema

[Abhinavexists]

Description

Fixed a bug where NotRequired fields in TypedDict caused a TypeError when converting to OpenAI function schema. The fix properly handles NotRequired and Required type annotations by:

Detecting and unwrapping NotRequired/Required annotations, Correctly excluding NotRequired fields from the required list in the OpenAI schema

Issue

Fixes: #34085

Dependencies

None

The implementation also includes a test case that validates the proper handling of TypedDict with NotRequired fields when converting to OpenAI function schema format.
