Fixes https://github.com/facebook/yoga/issues/1417 This dramatically simplifies the matrix of Node vs web, ASM vs WASM, sync vs async compilation, or CommonJS vs ES Modules. We have one variant, using without, with ESModule top-level await to do async compilation. Web/node share the same binary, and we base64 encode the WASM into a wrapper JS file for compatibility with Node and bundlers. After this change we target: This has some downsides, like requiring an environment with top level await, but also has upsides, like a consistent, sync looking API compatible with older Yoga, and mitigating TypeScript issues with package exports and typings resolution. ## Test Plan 1. `yarn test` 2. `yarn lint` 3. `yarn tsc` 4. `yarn build` website-next 5. Locally test website 5. Examine package artifact created by GitHub
