This is intended for TLS client auth with Windows CAPI- and CNG-backed keys
which implement sign over sign_raw and do not support all hash functions. Only
plumbed through RSA for now.

The only alias, EVP_PKEY_RSA2, is handled programmatically. ASN1_PKEY_ALIAS and
ASN1_PKEY_DYNAMIC are then unused and unexported and can be removed.

Factor the AlgorithmIdentifier portions of ASN1_item_sign and ASN1_item_verify
out. This makes it possible to initialize a signature context from an
AlgorithmIdentifier without needing the data parsed into an ASN1_ITEM/void*
pair and reserialized.

Custom RSA and ECDSA keys may not expose the key material. Plumb and "opaque"
bit out of the *_METHOD up to EVP_PKEY. Query that in ssl_rsa.c to skip the
sanity checks for certificate and key matching.

Converting check_autoarg from a macro to a function lost the behavior. Instead,
just move the logic into p_rsa.c which was the only EVP_PKEY implementation
that even needed the flag.
Also document this behavior on each of the functions. Make note of the out =
NULL case only returning the maximum output size, and not necessarily the
actual size.
For testing, update example_sign to determine the signature size using the NULL
behavior rather than querying the RSA key.
