[php-wasm/universal] Try require() before dynamic imprt in comlink-sync.ts (#2363)

## Motivation for the change, related issues

#2317 introduced a
dynamic import in a CJS code path (`comlink-sync.ts`). Node 20 requires
a `--experimental-vm-modules` flag to run dynamic imports in such a
context. This PR tries calling `require()` first to make it all work
again.

## Testing Instructions (or ideally a Blueprint)

Confirm the `test-built-npm-packages` test passed.
