feat(cloudflare): Migrate to dataCollection

[chargome]

Migrates the Cloudflare SDK from sendDefaultPii to the new dataCollection spec, without changing default behavior (the breaking default flips are deferred to v11).

• request.ts: Pass client.getDataCollectionOptions() to httpHeadersToSpanAttributes instead of the sendDefaultPii boolean. Header/cookie filtering is now driven by the resolved dataCollection.

• sdk.ts: requestDataIntegration is configured from dataCollection, but cookies are kept off by default (Cloudflare's historical behavior) unless the user opts in via sendDefaultPii or
  dataCollection.cookies. Marked TODO(v11) to drop this gate and let cookies default on (denylist-filtered) per spec ([v11] Migrate cookie / requestData gating to dataCollection #21260).

• httpServer.ts: maxRequestBodySize continues to default to 'medium' (bodies captured by default, matching the Node SDK and pre-migration behavior). Marked TODO(v11) to gate body capture on
  dataCollection.httpBodies ([v11] Gate incoming HTTP body capture on dataCollection.httpBodies #21258).

Fixes#20934
