Support cipher provider "iv state"

Some modes (e.g., CBC and OFB) update the effective IV with each
block-cipher invocation, making the "IV" stored in the (historically)
EVP_CIPHER_CTX or (current) PROV_CIPHER_CTX distinct from the initial
IV passed in at cipher initialization time. The latter is stored in
the "oiv" (original IV) field, and has historically been accessible
via the EVP_CIPHER_CTX_original_iv() API. The "effective IV" has
also historically been accessible, via both EVP_CIPHER_CTX_iv()
and EVP_CIPHER_CTX_iv_noconst(), the latter of which allows for
*write* access to the internal cipher state. This is particularly
problematic given that provider-internal cipher state need not, in
general, even be accessible from the same address space as libcrypto,
so these APIs are not sustainable in the long term. However, it still
remains necessary to provide access to the contents of the "IV state"
(e.g., when serializing cipher state for in-kernel TLS); a subsequent
reinitialization of a cipher context using the "IV state" as the
input IV will be able to resume processing of data in a compatible
manner.

This problem was introduced in commit
089cb623be76b88a1eea6fcd135101037661bbc3, which effectively caused
all IV queries to return the "original IV", removing access to the
current IV state of the cipher.

These functions for accessing the (even the "original") IV had remained
undocumented for quite some time, presumably due to unease about
exposing the internals of the cipher state in such a manner.

Note that this also as a side effect "fixes" some "bugs" where things
had been referring to the 'iv' field that should have been using the
'oiv' field. It also fixes the EVP_CTRL_GET_IV cipher control,
which was clearly intended to expose the non-original IV, for
use exporting the cipher state into the kernel for kTLS.

Allow oversized buffers for provider cipher IV fetch

When we're fetching an IV, there's no need to enforce that the
provided buffer is exactly the same size as the IV we want to
write into it. This might happen, for example, when
EVP_CIPHER_CTX_iv_noconst() passes sizeof(ctx->iv) (that is,
EVP_MAX_IV_LENGTH) for an AES-GCM cipher that uses a shorter IV.
AES-OCB and CCM were also affected.

OSSL_CIPHER_PARAM_IV can be accessed both as an octet string and as
an octet pointer (for routines like EVP_CIPHER_CTX_iv() that are
in a nebulous undocumented-and-might-go-away-eventually state),
the latter for when there is need to modify the actual value in
the provider.

Make sure that we consistently try to set it as both the string and pointer
forms (not just octet string) and only fail if neither version succeeds. The
generic cipher get_ctx_params routine was already doing so, but the
AES-variant-, GCM-, and CCM-specific ones were not.
