fix(next-swc): correct path interop to filepath for wasm (#65633)
### What
For loading wasm, path interop to absolute file path occurs in here
(https://github.com/vercel/next.js/blob/canary/packages/next/src/build/swc/index.ts#L1249)
already so shouldn't pre-populate import path when call loading wasm to
make internal path operation
(https://github.com/vercel/next.js/blob/canary/packages/next/src/build/swc/index.ts#L1247)
work.
