wolfcrypt/src/asn.c: fix -Wstringop-truncation from gcc-16.0.0_p20260104 in KeyPemToDerPassCb().

wolfcrypt/src/wc_port.c:
* fixes for readability-implicit-bool-conversion in wolfSSL_Atomic_Ptr_CompareExchange().
* refactor initRefCount as a wolfSSL_Atomic_Int, unless !WOLFSSL_ATOMIC_OPS, for thread safety.

wolfcrypt/src/sha512.c: fix underinitialization and config-dependent leak paths in InitSha512_Family().

wolfcrypt/test/test.c: in random_bank_test(), add a missing WC_DRBG_BANKREF gate, and fix wc_rng_bank_init(bank, ...) to pass _FLAG_NO_VECTOR_OPS to set up .sha_method test.
