Lennart Poettering 0df41e9329 cryptenroll: expose enrollment as an io.systemd.CryptEnroll Varlink service
Add a Varlink interface for systemd-cryptenroll, building on the EnrollContext
introduced previously. A single Enroll method covers password, recovery-key and
FIDO2 enrollment; PKCS#11 and TPM2 are not exposed for now (they are not
part of the EnrollMechanism allowlist, so the generic InvalidParameter error
applies). A ListSlots method enumerates the currently enrolled keyslots.

The dispatcher populates the same EnrollContext the command line uses and then
runs the shared enroll_now()/prepare_luks()/wipe_slots() paths, so both
front-ends behave identically. FIDO2 enrollment that requires user presence
reports an imminent touch via a non-terminating "state":"touch" reply when the
caller passes 'more'. Credential material (password, FIDO2 PIN, recovery key)
is handled as sensitive, and key files may be passed either by path or as an
fd index.

The server is allocated root-only plus caller's-own-UID, with the listening
socket created in 0644 mode.
