php-in-php: drop Type::initialize always-on openssl/hash/json/libcrypt/password/random_bytes ensureLinked — lazy Jit* ABI (peer #34327)

Problem

Type::initialize() on the non-STANDALONE path still eagerly NestedJITs openssl encrypt/sign/digest/pbkdf2, hash crypto (+ equals/algos), json encode/decode, libcrypt, password crypto/random_bytes, and StringRandomBytes even when the script never calls those builtins. Call sites already ensureLinked before lookup (or need a one-line JitRandomBytes ensureLinked).

php-src reference

• php/php-src ext/openssl — encrypt/decrypt, sign/verify, digest, pbkdf2
• php/php-src ext/hash/hash.c — hash / hash_hmac / hash_equals / hash_*_algos
• php/php-src ext/json — json_encode / json_decode
• php/php-src ext/standard/crypt.c / password.c / random.c

PHP implementation target

• lib/JIT/Builtin/Type.php — remove eager ensureLinked for listed runtimes
• ext/standard/JitRandomBytes.php — StringRandomBytes::ensureLinked before lookup (gap vs other Jit* owners)
• Update TypeDead*StillEnsureLinks* guards for those ABIs to call-site ownership
• Unit shrink test peer TypeDeadTypeInitializeLazyCryptoJsonRuntimeShrinkTest

Repro

./script/aot-smoke.sh
./script/docker-exec.sh -- bash -lc './script/cold-build-check.sh'

Done when

• Type::initialize no longer eagerly ensureLinks listed crypto/json/password/random runtimes
• openssl/hash/json/crypt/password/random_bytes still match Zend via call-site ensureLinked
• ./script/aot-smoke.sh stays 8/8
• cold-build-check ok
• No new runtime/*.c
