go1.27 uuid support

[tulzke]

Go 1.27 adds uuid.UUID to the standard library. It would be useful for go-tarantool to support this type for Tarantool's UUID MessagePack extension (ext type 2) alongside the currently supported UUID implementations.

Since vmihailenco/msgpack allows only one Go type to be registered for a given ext type, adding it to the existing registration would be a breaking change. We should consider providing stdlib UUID support through a separate opt-in package or another explicit registration mechanism.

Hello there!

I've tried smth with adding explicit extra packages and all the staff, but due to vmihailenco/msgpac limits it'd always break for migration period: any service have to replace all previous google/uuid usages with stdlib ones and completely drop previous pkg usagfe

Maybe it's not that bad to patch module with smth like 610 since the source code will be rewritten in any case?
