[Turbopack] fail safe on binary import to string

What?

This fixes an issue with Turbopack when importing binary files like image, videos.

Why?

Currently the build process will crash if Turbopack tries to convert a binary file import to a string.
For next-video this functionality is required though we don't use the binary content. It's more about the import path and file name.

example output:

Failed to compile

./videos/coblocks-ai.mp4.json.json
Code generation for chunk item errored
An error occurred while generating the chunk item [project]/videos/coblocks-ai.mp4.json.json (json)

Caused by:
- failed to convert rope into string
- invalid utf-8 sequence of 1 bytes from index 35

How?

This is a simple try / catch around the content to string conversion. If the conversion fails the content is set to an empty string for now. I considered converting to base64 so it could still be used in the JS Webpack loader but I have concerns that could slow down the build process too much.

In the future I hope Turbopack can support the Webpack "raw" option to pass the content as bytes.
