php-in-php: drop leftover Type always-on xmlrpc ABI shells (ext/xmlrpc/xmlrpc.c)

Problem

Builtin\Type::register still always-on addFunctions empty __compiler_xmlrpc_encode_value / __compiler_xmlrpc_decode decls. NestedJIT/AOT bodies are owned by StringXmlrpc (getNamedFunction first; JitVmHelperLink::ensureBridge / decode emit create the symbol if absent). Leftover Type empty decls risk name.1 vs Runtime ABI drift (#31894 / #32122) — same class as #32897 json / #32250 (already dropped __compiler_xmlrpc_encode_array).

Path	Today	Target
User-script xmlrpc_encode() / xmlrpc_decode()	ext/xmlrpc/JitXmlrpc → StringXmlrpc	unchanged
Type always-on empty decl	present	removed; StringXmlrpc::ensureLinked from Type::initialize

php-src reference

• php/php-src ext/xmlrpc/xmlrpc.c — PHP_FUNCTION(xmlrpc_encode) / xmlrpc_decode

PHP implementation target

• lib/JIT/Builtin/Type.php — drop always-on xmlrpc ABI shells; ensureLinked StringXmlrpc from Type::initialize
• Keep ownership in StringXmlrpc / ext/xmlrpc/JitXmlrpc.php
• Update TypeDeadCompilerAbiRuntimeShrinkTest sentinel that still requires registerFunction('__compiler_xmlrpc_encode_value'

Done when

• Type.php no longer addFunctions the xmlrpc ABIs
• AOT xmlrpc_encode / xmlrpc_decode still match Zend
• ./script/aot-smoke.sh stays 8/8
• Shrink unit test (peer TypeDeadJsonAbiRuntimeShrinkTest)

[PurHur]

claim: php-runtime-migration — starting this run (drop leftover Type always-on xmlrpc ABI shells; peer #32897; aot-smoke 8/8)

[PurHur]

claim: maintainer-trust-lane — implementing Type xmlrpc ABI shell drop this run (peer #32897 / #32893; leftover of #32122 class).

[PurHur]

release claim: switching to Trust regression from #32900 — AOT InfNan (#32326) fails looking up __compiler_json_encode_array because bridges register after body emit. Will reclaim xmlrpc after that lands.
