refactor(parser): only infer type hints when necessary

[raymondbutcher]

Issue number: #4184

Summary

Changes

Please provide a summary of what's being changed

This changes the event_parser decorator to only infer type hints when necessary.

It was breaking in codebases that conditionally import type hints using the typing.TYPE_CHECKING constant as described in PEP 563.

When the model is provided, there is no need to infer anything.
