[turbopack] Make it possible to synchronously access native bindings (#85787) ## Enable synchronous access to native bindings ## What? This PR refactors the SWC bindings loading mechanism to support synchronous access to bindings after they've been loaded. It introduces new functions `installBindings()` and `getBindingsSync()` to properly manage the bindings lifecycle. `installBindings` is called early by tools that rely on them. There were of course a few complexities: * webpack loaders need to defensively install bindings to support being run by webpack * the hacky `loadNativeSync` method used by `transformSync` remains required due to the jest-transformer API (i didn't see a clear initialization location). * the `experimental.useWasmBinary` configuration is broken by design * if the config is `next.config.ts` when we load SWC to transpile it, but that requires the native bindings, so we might load native bindings even when you ask for wasm. I added a warning message for this case and the workaround is to use the node native transpilation support. * this should probably be a command line flag if it is important * we need to lazily load the `swc/index.ts` module since it transitively loads `react` which reads `NODE_ENV` and various next entrypoints might modify that. ## Why? This makes it clearer that we are correctly applying the `useWasmBinary` option and can simplify some code paths that now don't need to be `async`. This will be important in a future PR where i move some parts of issue formatting into rust/wasm. Having those APIs be async will decrease their usability.
