ref(build): Use rollup config function for @sentry/browser (#4668)
As part of centralizing and unifying our CDN rollup config, this uses the config generation function introduced in #4650 to generate the config for all browser bundles. Unlike many of the other PRs in this series, this one does actually have an effect on certain bundles, to wit: - `_mergeOptions` is no longer a protected-from-minifcation property, as it's about to be extracted into a stand-alone function. (See #4625.) - Up until this point, one difference between the `@sentry/browser` rollup config and all of the other rollup configs was the former's use of the `__SENTRY_NO_DEBUG__` flag to suppress logs in the minified bundles. Rather than add a parameter to the function controlling whether or not each package should use the flag, I decided it was better to just apply the flag to all minified bundles.
