MB-72554: Handle deprecated analysis components

Analysis components (analyzers, tokenizers, token maps, token filters) can
be removed from the registry over time. Previously, an index built with one
of these would become impossible to open, rebuild, or query, since lookups
failed with a plain "not registered" error.

Now such a name is reported as deprecated instead. Opening, rebuilding, and
indexing continue to work for an existing mapping that references one, with
affected fields indexed without analysis. Queries that need to analyze text
with a deprecated component still fail, but with an error that identifies
it as deprecated rather than unknown. New mappings should reject these
components by checking Validate's error for registry.ErrDeprecatedComponent.
