feat(remix): Auto-wire orchestrion build-time instrumentation

`sentryRemixVitePlugin()` now adds the orchestrion bundler plugin automatically, so bundled SSR
builds get `diagnostics_channel` publishers injected with no manual plugin setup. Remix was the
last metaframework SDK still requiring users to wire `sentryOrchestrionPlugin()` themselves.

Builds targeting workerd (Cloudflare Pages, Hydrogen/Oxygen) are skipped: they instrument through
`instrumentBuild()` from `@sentry/remix/cloudflare` and never subscribe to the injected channels.

Fixes #23986
Refs #22632

+The plugin now also applies the build-time instrumentation transform. If you added `sentryOrchestrionPlugin()` from `@sentry/server-utils/orchestrion/vite` to your Vite config manually, remove it. Opt out with `sentryRemixVitePlugin({ buildTimeInstrumentation: false })`.
