[meta-oe][PATCH 3/3] libspdm: Fix build with openssl 3.5

[Khem Raj <raj.khem@gmail.com>]

Backport new API signature, since the vendored version of openssl in
libspdm is 3.0.14, asn1.h has to sync for providing it.

+Subject: [PATCH] Backport API introduced in openssl 3.5.0
+
+This commit [1] introduced this new API which is used by pem.h from
+openssl and it should be provided by asn1.h which is vendored here so
+it goes out of sync and causes build errors e.g
+
+In file included from ./os_stub/cryptlib_openssl/pk/x509.c:18:
+/usr/include/openssl/pem.h:399:28: error: unknown type name 'OSSL_i2d_of_void_ctx'
+  399 | int PEM_ASN1_write_bio_ctx(OSSL_i2d_of_void_ctx *i2d, void *vctx,
