cue: add LanguageVersion
This makes the current language version available as part of the public
API.
Currently there is no way in the public API to obtain access to the
current language version as defined in `cueversion.LanguageVersion`.
When users of the Go API are wanting to create a module.cue version
manually that corresponds to the current language version, that would be
useful.
Fixes #3246.
