feat: update eslint to v8

[JPeer264]

This upgrades our internal eslint config to use v8. Theoretically this is considered a breaking change. Since this is an internal @sentry-internal/* package, we can release this in a non-breaking fashion

With v8 couple of changes came. Some of them are affecting us, which required file changes:

• simple-import-sort/import got couple of fixes
• "Unused eslint-disable directive": Unused "eslint-disable" comments are now detected and marked as error
• import/export got a false positive, which affects most of our index barrel files (I didn't want to disable it entirely, so I added a global disable in each affected barrel file)
  • tracked here: import/export false positive with star reexports import-js/eslint-plugin-import#703
