Split OCI Image Index from Docker Manifest List
Move implementation of the index from the manifestlist package to the ocischema package so that other modules making empty imports support the manifest types their authors would expect. This is a breaking change to distribution as a library but not the registry.

As OCI 1.0 released the manifest and index together, that is a good package from which to initialise both manifests. The docker manifest and manifest list remain in separate packages because one was released later.

The image index and manifest list still share common code in many functions not intended for import by other modules.

Align code to match order of fields
This is just cosmetic; alighn the fields with the order in which they appear
in the struct (and JSON output).

Descriptor: align field order with OCI image specification
I am looking at aligning the types defined in this repository with the
OCI image specification, and potentially exchanging local types with
those from the specification.

This patch is a stepping-stone towards that effort, but as this changes
the format of the serialized JSON, I wanted to put this up first before
proceeding with the other work in case there are concerns.

manifest: improve test output and use const
Use consts to make clear these values are fixed, and improve the output
to make it clearer which part is the expected output, and which part
the actual.

Before this:

go.mod: change imports to github.com/distribution/distribution/v3
Go 1.13 and up enforce import paths to be versioned if a project
contains a go.mod and has released v2 or up.

The current v2.x branches (and releases) do not yet have a go.mod,
and therefore are still allowed to be imported with a non-versioned
import path (go modules add a `+incompatible` annotation in that case).

However, now that this project has a `go.mod` file, incompatible
import paths will not be accepted by go modules, and attempting
to use code from this repository will fail.

This patch uses `v3` for the import-paths (not `v2`), because changing
import paths itself is a breaking change, which means that  the
next release should increment the "major" version to comply with
SemVer (as go modules dictate).

60d9c5dfad Handle OCI manifests and image indexes without a media type
In the OCI image specification, the MediaType field is reserved
and otherwise undefined; assume that manifests without a media
in storage are OCI images or image indexes, and determine which
by looking at what fields are in the JSON. We do keep a check
that when unmarshalling an OCI image or image index, if it has
a MediaType field, it must match that media type of the upload.

1d47ef7b80 Check media types when unmarshalling manifests
When unmarshalling manifests from JSON, check that the MediaType field
corresponds to the type that we are unmarshalling as. This makes sure
that when we retrieve a manifest from the manifest store, it will have
the same type as it was handled as before storing it in the manifest
store.
