8b7b9aac44 Fix a HPKE API to put libctx, propq as last (optional parameters).
This keeps the interface consistent with other HPKE API's.

d9ed3068df Refactoring some operations to avoid repeated calls
Fetch the EVP_CIPHER for aead in OSSL_HPKE_CTX_new()
to avoid re-fetching on each aead operation.

Save kem/kdf/aead_info in OSSL_HPKE_CTX.

450f96e965 Fix Coverity issues in HPKE
CID 1517043 and 1517038: (Forward NULL) - Removed redundant check that is already
done by the caller. It was complaining that it checked for ctlen == NULL
and then did a goto that used this *ctlen.

CID 1517042 and 1517041: (Forward NULL) - Similar to above for ptlen in
hpke_aead_dec()

CID 1517040: Remove unneeded logging. This gets rid of the warning
related to taking the sizeof(&)

CID 1517039: Check returned value of  RAND_bytes_ex() in hpke_test

CID 1517038: Check return result of KEM_INFO_find() in
OSSL_HPKE_get_recomended_ikmelen. Even though this is a false positive,
it should not rely on the internals of other function calls.

Changed some goto's into returns to match OpenSSL coding guidelines.
Removed Raises from calls to _new which fail from malloc calls.

ad062480f7 Implements Hybrid Public Key Encryption (HPKE) as per RFC9180.
This supports all the modes, suites and export mechanisms defined
in RFC9180 and should be relatively easily extensible if/as new
suites are added.  The APIs are based on the pseudo-code from the
RFC, e.g. OSS_HPKE_encap() roughly maps to SetupBaseS().  External
APIs are defined in include/openssl/hpke.h and documented in
doc/man3/OSSL_HPKE_CTX_new.pod.  Tests (test/hpke_test.c) include
verifying a number of the test vectors from the RFC as well as
round-tripping for all the modes and suites.  We have demonstrated
interoperability with other HPKE implementations via a fork [1]
that implements TLS Encrypted ClientHello (ECH) which uses HPKE.

@slontis provided huge help in getting this done and this makes
extensive use of the KEM handling code from his PR#19068.
