This is a companion to https://github.com/WordPress/gutenberg/pull/65460 that requires syncing in WordPress Core. Namely, the block-library changes require registration with their updated script module IDs so that the blocks continue to work correctly.
They key improvement is script modules registration is handled in one central place, and a combined asset file is used to improve the performance by avoiding multiple disk operations for every individual file.
