Skip wasmBinaryFile initialization on pthread workers

sbc100 · sbc100 · commit 3fd95b683217 · 2024-04-25T09:32:28.000-07:00
Delay the search for the wasm binary (e.g. using `locateFile`) so that it does not run on pthread workers (or weasm workers) where `Module.instantiateWasm` is set. The wasm file is always received via postMessage when running on the worker so we shouldn't ever be calling locateFile in this situation. See #21826 and #21827
