fix(deno): Re-export portable helpers that Cloudflare exposes - #25491

Cloudflare runs on workerd with no Node APIs, but it still exports more
than Deno. The missing exports already work in Deno, because they come
from `@sentry/core` and `@sentry/server-utils`, which Deno depends on.

The manual AI client helpers matter most. Deno does not inject
diagnostics channels by default, so `instrumentOpenAiClient` and the
other `instrument*` helpers are the documented way to get AI spans
there.

Deno now re-exports `addIntegration`, `withActiveSpan`,
`getSpanDescendants`, `setConversationId`, `createConsolaReporter`,
`growthbookIntegration`, `moduleMetadataIntegration`,
`trpcMiddleware`, `prismaIntegration`, the OpenAI, Anthropic, Google
GenAI, Mistral, TypeSafe, LangChain and LangGraph helpers, and the
`FlueOptions` type. Deno also gets `initWithoutDefaultIntegrations` and
`getDefaultIntegrationsWithoutPerformance`, to match Node and Bun. The
default integration set does not change.

Some Cloudflare exports stay out. `instrumentWorkersAiClient` wraps a
binding that exists only on Cloudflare. `spotlightIntegration` and
`httpServerIntegration` live in the Cloudflare package, not in a shared
entry point, so they need more than a re-export. `parameterize` was in
the issue, but Cloudflare no longer exports it.

Fixes #23896
Fixes JS-3522
