licensing: fix up licensing and copyright

Move ociregistry/LICENSE to the root of the repo. This Apache
2.0 license (which we inherit from original code) applies to all Go
modules in this repo. Per https://go.dev/ref/mod#vcs-license this then
means the LICENSE applies to all modules in the repository:

    When the go command creates a .zip file for a module that is not in
    the repository root directory, if the module does not have a file
    named LICENSE in its root directory (alongside go.mod), the go
    command will copy the file named LICENSE from the repository root
    directory if it is present in the same revision.

Add copyright headers to all .go and .cue files that do not have them.
They are, by definition, files that have been added by work done by CUE
Labs in the fork from original work.

Leave original Google copyright headers in .go files that have them.
