feat(pyreqwest): Support data_collection filtering for URL query params

[ericapisani]

Previously the pyreqwest integration only redacted URL query params
and fragments based on send_default_pii, always leaking the full
query string when PII collection was enabled. Now the
data_collection experiment's url_query_params allow/deny list is
applied to spans and breadcrumbs, matching the behaviour already
shipped for httpx.

Legacy (non span-streaming) breadcrumbs still report the bare URL
without the query string, but the query value itself is filtered
consistently with span streaming.

Fixes PY-2746
Fixes #7281
