Richard Levitte 70a7dd6f96 X509: Rename X509_set0_sm2_id() and friends
- X509_set0_sm2_id() -> X509_set0_distinguishing_id()
- X509_get0_sm2_id() -> X509_get0_distinguishing_id()
- X509_REQ_set0_sm2_id -> X509_REQ_set0_distinguishing_id()
- X509_REQ_get0_sm2_id -> X509_REQ_get0_distinguishing_id()

The reason for this rename is that the SM2 ID isn't really a unique
SM2 data item, but rather a re-use of the Distinguished that is
defined in ISO/IEC 15946-3 as well as in FIPS 196, with no special
attribution toward any algorithm in particular.

Fixes #11293

* X509_REQ_INFO is handled in an unusual way to get round
* invalid encodings. Some broken certificate requests don't
* encode the attributes field if it is empty. This is in
* violation of PKCS#10 but we need to tolerate it. We do
* this by making the attributes field OPTIONAL then using
* the callback to initialise it to an empty STACK.
*
* This means that the field will be correctly encoded unless
* we NULL out the field.
*
* As a result we no longer need the req_kludge field because
* the information is now contained in the attributes field:
* 1. If it is NULL then it's the invalid omission.
* 2. If it is empty it is the correct encoding.
* 3. If it is not empty then some attributes are present.
