Check tag class and constructed bit in d2i_ASN1_OBJECT.

d2i_ASN1_OBJECT had a similar set of bugs in as in
https://boringssl-review.googlesource.com/c/boringssl/+/49866.

This does not affect any other d2i functions. Those already go through
the ASN1_ITEM machinery.

Update-Note: d2i_ASN1_OBJECT will now notice more incorrect tags. It was
already checking for tag number 6, so it is unlikely anyone was relying
on this as a non-tag-checking parser.
