php-in-php: drop leftover Type always-on addcslashes/stripcslashes ABI shells (ext/standard/string.c)

Problem

Builtin\Type::register() still addFunctions empty always-on shells for __compiler_addcslashes and __compiler_stripcslashes on every JIT/AOT module. StringCslashes already owns those ABIs (getNamedFunction first + JitVmHelperLink::ensureBridge), but leftover Type empty decls can mint addcslashes.1 when Runtime ABI drift lands (#31894 / #32122 class).

php-src reference

• php/php-src ext/standard/string.c — PHP_FUNCTION(addcslashes) / PHP_FUNCTION(stripcslashes)

PHP implementation target

• lib/JIT/Builtin/Type.php — remove always-on addcslashes/stripcslashes rows; Type::initialize ensureLinkeds StringCslashes (and ensureStripcslashes / ensureStandaloneBodies as needed)
• Keep StringCslashes / CslashesJitHelper; no new runtime/*.c
• Leave __compiler_convert_uuencode Type rows alone (sentinel for peer shrink tests)

Repro

grep -n "__compiler_addcslashes\|__compiler_stripcslashes" lib/JIT/Builtin/Type.php

Done when

• Type no longer always-declares/registers the two ABIs
• Type::initialize ensureLinks StringCslashes
• ./script/aot-smoke.sh stays 8/8
• Targeted phpunit shrink test green
• AOT addcslashes/stripcslashes still match Zend
