Refresh vendored MEOS-API from master

Regenerated vendor/meos-api/meos-idl.json via make vendor-meos-api against
MobilityDB/MEOS-API@master + MobilityDB@master. Picks up the improved int8/bool
type recovery (stale 'int' -> 'bool') and the trgeoinst_make->trgeometryinst_make
rename. Resolves the scheduled vendor-drift check (run 27612874956).
