feat(multipart-parser: support Response parsing using the Request code

[lpetre]

This is a simple typing and testing change to allow Responses to be parsed in addition to Requests.

My use-case is that I'm using fetch to call an API that returns multipart responses and I want to use a nice library to handle the reply.

Testing Strategy:

$ pnpm --filter @remix-run/multipart-parser run test
