fix: Make pytest config compatible with newer pytest

[antznette1]

What this PR does / why we need it:

• Update sdk/python/pytest.ini to avoid relying on internal _pytest.warning_types.* warning classes (breaks on newer pytest).
• Fix Windows multiprocessing start method selection (sys.platform is win32, not windows).
• Avoid importing optional integration-only dependencies at conftest.py import time (so test collection doesn’t hard-fail when optional deps aren’t installed).

Why we need it:

• Unblocks local test runs on newer pytest versions and improves Windows contributor experience.

Testing

• Local: verified pytest no longer fails early due to invalid warning class / Windows fork start method.
