pw_blob_store: Add support for deferred writes

- Add support for deferred writes.
- Use DeferredWriter that is similar to BlobWriter, but does deferred
  writes.
- Decouple write buffer size from flash write size.
- Return DATA_LOSS for all write errors and treat blob as unwritable
  until erased.
