Most content proxy operations normalize remote RPC errors before
returning them, including stream receive errors from Walk and write
errors from the remote writer. remoteReaderAt.ReadAt was an outlier and
returned raw status errors from Read and Recv.
Callers that use content.ReadBlob through the proxy can then fail
errdefs checks, such as treating concurrent content deletion as
NotFound.
Convert non-EOF read stream errors with errgrpc.ToNative so ReaderAt
matches the rest of the content proxy while preserving io.EOF.

Allow the api to stay at the same v1 go package name and keep using a
1.x version number. This indicates the API is still at 1.x and allows
sharing proto types with containerd 1.6 and 1.7 releases.
