php-in-php: drop leftover Type always-on sprintf/printf/number_format ABI shells (ext/standard/formatted_print.c)

Problem

Builtin\Type::register still always-on addFunctions empty __compiler_sprintf / __compiler_printf / __compiler_number_format decls. NestedJIT/AOT bodies are owned by StringFormat (getNamedFunction first, then addFunction if absent; thin AOT already calls implementIfDeclared from JitSprintf / JitPrintf / JitNumberFormat). Leftover Type empty decls risk name.1 vs Runtime ABI drift (#31894 / #32122) — same class as #32897 json / #32902 xmlrpc. These symbols sit on the float→string path (#31963).

php-src reference

• php/php-src ext/standard/formatted_print.c — PHP_FUNCTION(sprintf) / printf / number_format

PHP implementation target

• lib/JIT/Builtin/Type.php — drop always-on format ABI shells; Type::initialize ensureLinkeds StringFormat
• Keep ownership in lib/JIT/Builtin/StringFormat.php + ext/standard/SprintfJitHelper.php

Done when

• Type.php no longer addFunctions __compiler_sprintf / __compiler_printf / __compiler_number_format
• AOT sprintf / printf / number_format still match Zend
• ./script/aot-smoke.sh stays 8/8
• Shrink unit test (peer TypeDeadXmlrpcAbiRuntimeShrinkTest)

Parent

• Trust: Release v1.1.0: fix cold-build-check compile_failed on hello world (LLVM Module.php line 180; re-#24302) #32122 / Fix: AOT link fails for EVERY binary — duplicate memset declaration #31894
• Peers: php-in-php: drop leftover Type always-on json ABI shells (ext/json/php_json.c) #32897 json, php-in-php: drop leftover Type always-on xmlrpc ABI shells (ext/xmlrpc/xmlrpc.c) #32902 xmlrpc, AOT: float→string conversion crashes — printf/number_format/json_encode/serialize/strval all segfault on floats #31963 float→string
