...and rename Blockly.blocks.all (blocks/all.js) to Blockly.libraryBlocks (blocks/blocks.js BREAKING CHANGE: (only) because the exports object from the `blocks_compressed.js` chunk will be accessed as `Blockly.libraryBlocks` instead of `Blockly.blocks.all` when the chunk is loaded in a browser via a `<script>` tag. There will be no changes visible when the chunk is loaded via ES module `import` or CJS `require`.
