build(replay): Use Monorepo's rollup config to build Replay

[Lms24]

This PR updates Replay's build config to use our monorepo's rollup config for building and transpiling the Replay integration. With this PR, we're introducing a breaking change because the tarball structure is going to change. However, this only breaks users who imported from package-internal paths directly and not from the top-level package.

More specifically, these are the changes:

• Move and rename./config/rollup.config.core.ts to ./rollup.npm.config.js which now uses our makeNPMConfigVariants and makeBaseNPMConfig rollup config helper functions to create ESM and CJS transpiled JS, just like in all our other packages. For now we have to change this to JavaScript but we can ofc revisit having TS-based rollup configs in the future.
  • Instead of bundling everything into the index.js files, this config now just transpiles the individual modules. This is how we do it in all our other packages. We might have to revisit this strategy for vendoring rrweb and bundling but we can build on top of this PR to do so.
• Move and rename ./config/rollup.worker.config.ts to ./rollup.worker.config.js (no changes)
• Update eslint configs
• Fix a few type errors I came across while performing these build changes
• Update package.json scripts so that they are in line with the scripts of our other packages. This should simplify the scripts a little.
• Revert fix(replay): Temporarily build Replay after other packages #6307 as we now transpile and check/build types separately, like we do with the rest of our packages.
• Revert fix(replay): Temporarily replace __DEBUG_BUILD__ with true #6341 as the__SENTRY_DEBUG__ flag is now set in our rollup helper functions

Besides executing unit tests and manually inspecting the transpiled output, I also tested these changes with a plain-js test app and it still seems to work.
