feat(build): introduce root build directory in @sentry/browser

Lms24 · lobsterkatie · Lms24 · commit e05a8394e14b · 2022-03-17T12:37:20.000+01:00
* add root build directory as the output directory for all module formats and bundles. This puts
  all build JS files and modules (bundles, esm, cjs) into one central build directory. Currently,
  `package.json`, Readme, License, etc. are still in the package root directories. This should
  keep things more organized and more clearly arranged.

* adjust `tsconfig.json` to build type declarations (*.d.ts) into a separate directory
  (`build/types`). This deduplicates the identical declarations that were peviously compiled
  into `dist` and `esm`.

* introduce `rootBuildDirectory` export in root `rollup.config.js` as it will (probably) be
  used in multiple packages and this lets us change the name for all of them at once.
