Support Sentry Logging in the JS Loader and CDN

[AbhiPrasad]

Description

You can now send structured logs to Sentry! See the docs here.

We don't have logging functionality exposed in the loader or a separate CDN bundle. We should add it.

We probably also need a shim then for non-logging bundles in case users enable logging first, add manual logger calls and then disable logging via the UI later. (i.e. similar to what we do with BrowserTracing and Replay)

Is there an estimated version for this feature? Thank you.

[AbhiPrasad]

No estimate yet, there's some other logging work that needs to get done in the js sdk before we get to this. It's on the roadmap though!
