Add the ability to unseal using recovery keys via an explicit seal option. (#18683)
* wip

* wip

* Got it 'working', but not happy about cleanliness yet

* Switch to a dedicated defaultSeal with recovery keys

This is simpler than trying to hijack SealAccess as before.  Instead, if the operator
has requested recovery unseal mode (via a flag in the seal stanza), we new up a shamir
seal with the recovery unseal key path instead of the auto seal.  Then everything proceeds
as if you had a shamir seal to begin with.

* Handle recovery rekeying

* changelog

* Revert go.mod redirect

* revert multi-blob info

* Dumb nil unmarshal target

* More comments

* Update vault/seal.go
