Add file backend support for Blob and related
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy --faster` does not report any errors
- [x] These changes fix#10851, related to #11131
- [x] These changes do not require tests because the implementation is partial and can't work alone
1. Add new backend to `Blob` and a `BlobImpl` struct to abstract multiple backends
2. Rewrite most interfaces of `Blob` to accommodate the change
3. Change the `read` behaviour of `FileReader`, considering the case when blob is file-backed and not cached
The design is still immature, welcome comments!
- [x] I used `DOMRefCell` to cache the bytes in `BlobImpl`, is it sound?
- [x] The interfaces (like `BlobImpl::get_bytes`) handle requests in a default-to-empty way when the inner `DataSlice` is not cached. It might be possible to handle this condition better.
