feat(boto3): Support data_collection filtering for URL query params

[ericapisani]

Previously the boto3 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 the span-streaming span
attributes and to breadcrumbs, matching the behaviour already shipped for
httpx and pyreqwest.

url.full now includes the filtered query string and fragment, and
url.query / url.fragment are omitted rather than reported as empty
strings when the request URL has none.

The legacy (non span-streaming) span path is left as-is.

Fixes PY-2745
Fixes #7280
