fix(session replay): dynamically import plugin-console-record

[jxiwang]

Summary

Break our rrweb-console-plugin import into a separate chunk.

We are now dynamically importing our Session Replay Plugin in order to prevent the rrweb-console-plugin package from adding ~40KB to our size.

Implications -

• To take advantage of code-splitting, the main session-replay-browser SDK is now an esm build.
• A new legacy build for non-esm compatible browsers.

I'd probably want to sync with you to better understand if there's any impact to how customers would install this and maybe how it'll fit into all the one line scripts we have.
