Add AutoFile without ser-type and ser-version and use it where possible #25285

   This was done in the context of #25284 , but I think it also makes sense standalone.

   The basic idea is that serialization type should not be initialized when it is not needed. Same for the serialization version.

   So do this here for AutoFile. CAutoFile remains in places where it is not yet possible.

    Code review ACK facc2fa7b8a218a0df6a19772e1641ea68dda2e3 The code change is straightforward and easy to review.

    However, I am not entirely happy about the naming of AutoFile versus CAutoFile I would personally prefer a more distinctive name.

    However, I am not entirely happy about the naming of AutoFile versus CAutoFile I would personally prefer a more distinctive name.

    CAutoFile is deprecated, only used in two remaining places: addrdb and tx/block serialization, and will be removed as a follow-up to #25284. So I left the name as is, but I am happy to append a scripted-diff here to rename CAutoFile to something else. Maybe LegacyAutoFile?

    OK, if it's going away soon™ i have no problem with this. There's something to be said for an intermediate rename, but also there's drawbacks in generating a bigger diff.

    I just imagined it's pretty frustrating for developers to have similarly named classes with slightly different behavior, it's not something to keep on the long run (it reminds me of the situation in net classes naming CAddress / CService / CNetAddr a bit, where, even though i've worked on this code for years keep forgetting what is what).
