This cleans up the story with
https://boringssl-review.googlesource.com/c/boringssl/+/46164. None of
our exported functions mutate ASN1_OBJECTS, with the exception of
ASN1_OBJECT_free, the object reuse mode of c2i_ASN1_OBJECT, and their
callers. Those functions check flags to correctly handle static
ASN1_OBJECTs.
For now, I've kept the struct definition in crypto/asn1 even though
ASN1_OBJECT is partially in crypto/obj. Since we prefer to cut
dependencies to crypto/asn1, we probably should rearrange this later.
I've also, for now, kept crypto/asn1/internal.h at C-style comments,
though our style story here is weird. (Maybe it's time to clang-format
crypto/asn1 and crypto/x509? Patches from upstream rarely directly apply
anyway, since we're a mix of 1.0.2 and 1.1.1 in crypto/x509.)
Update-Note: ASN1_OBJECT is now opaque. Callers should use accessors.

The implementation is a little goofy, but OBJ_dup internally makes a
copy of all the data.
