Running in embedded V8 that doesn't support import

[YarnSaw]

I'm running an embedded v8 engine with Dawn integrated for webgpu that doesn't support import. On older versions of onnxruntime, I was polyfilling fetch to supply ort-wasm-simd-threaded.wasm and ort-wasm-simd-threaded.jsep.wasm, loaded during the startup of the environment, which worked for version 1.17.0 of onnxruntime.

Trying to update to the most recent version for better webGPU support, the system for loading modules was massively changed in commit 036fcd9 to use the Worker API (which is also unsupported in my environment), as well as dynamic imports. Is there any way to default the behaviour back to fetch/eval that use to exist, or alternative method I can polyfill to make things work? I can't polyfill import since it's a keyword.
