chore: Move everything into package/ (#1745)

* Move everything into package * Remove .DS_Store * Move scripts and eslintrc to package * Create CODE_OF_CONDUCT.md * fix some links * Update all links (I think) * Update generated docs * Update notice-yarn-changes.yml * Update validate-android.yml * Update validate-cpp.yml * Delete notice-yarn-changes.yml * Update validate-cpp.yml * Update validate-cpp.yml * Update validate-js.yml * Update validate-cpp.yml * Update validate-cpp.yml * wrong c++ style * Revert "wrong c++ style" This reverts commit 55a3575589c6f13f8b05134d83384f55e0601ab2.
