This consists of just the base MergeOp with support for merging LLB
results that include deletions using hardlinks as the efficient path
and copies as fallback.

Before this, descriptor handlers were not included with calls to the
exporter, which then sometimes called LoadRef and failed to get a ref
because it was lazy. This change results in the DescHandlers of the
already loaded refs to get plugged into context so they can be re-used
by the exporter if it needs to load the ref again.

FromRemote now calls CheckDescriptor to validate
if the blob still exists. Otherwise cache loading
fallback does not get triggered because cache is
actually lazily pulled in only on exporting phase.

There are a few goals with this refactor:
1. Remove external access to fields that no longer make sense and/or
won't make sense soon due to other potential changes. For example,
there can now be multiple blobs associated with a ref (for different
compression types), so the fact that you could access the "Blob"
field from the Info method on Ref incorrectly implied there was just
a single blob for the ref. This is on top of the fact that there is
no need for external access to blob digests.
2. Centralize use of cache metadata inside the cache package.
Previously, many parts of the code outside the cache package could
obtain the bolt storage item for any ref and read/write it directly.
This made it hard to understand what fields are used and when. Now,
the Metadata method has been removed from the Ref interface and
replaced with getters+setters for metadata fields we want to expose
outside the package, which makes it much easier to track and
understand. Similar changes have been made to the metadata search
interface.
3. Use a consistent getter+setter interface for metadata, replacing
the mix of interfaces like Metadata(), Size(), Info() and other
inconsistencies.

Allow user to choose the compression type for layer data. Gzip is
default compression for layer exporter, which consume more Cpu resources
and take long time to export. With compression option, user can use
nocompressed option to export to save time. And future, zstd is one new
option for end-user.

As manifests may be temporary if the same image is built in parallel one build can delete the manifest+config before the export for another finishes.

It is enhancement which allows to unpack image into containerd
snapshotter storage by `--output type=image,<.>=<.>,unpack=true`.
In order to support this feature, we needs to extend the Snapshotter
witwh `Name() string` function. Because we needs to set gc label for
snapshotter which need snapshotter name.

Use vertex platform instead of the current system one. This shouldn't break any cache unless qemu was used. Even when qemu was used the issue would not cause any cache collisions because the base images for run were scoped by platform, but better to stop using invalid data for cache key calculation.
