php-in-php: drop leftover Type always-on env_local/putenv ABI shells (ext/standard/basic_functions.c)

Problem

Builtin\Type::register() still ensureExternalFunctions empty always-on shells for __compiler_env_local_lookup and __compiler_env_register_putenv on every JIT/AOT module. Runtime owner already declares module-locally via JitEnvLocalKernel (getNamedFunction first) and Type::register() already calls EnvLocalRuntime::ensureLinked():

• EnvLocalRuntime / JitEnvLocalKernel — env overlay lookup + putenv register

Leftover Type empty decls vs Runtime ABI drift mints name.1 (#31894 / #32122 class). These two are the last forever-on Type $libcFns-era table after #32202/#32665.

php-src reference

• php/php-src ext/standard/basic_functions.c — zif_getenv / zif_putenv

PHP implementation target

• lib/JIT/Builtin/Type.php — remove always-on __compiler_env_local_* rows + dead ensureExternalFunction
• ext/standard/JitEnvLocalKernel.php — keep ABI ownership (getNamedFunction first)
• unit shrink test peer TypeDeadGetenvAbiRuntimeShrinkTest

Done when

• Type.php does not always-declare the two ABI names
• JitEnvLocalKernel still owns the ABI
• aot-smoke.sh stays 8/8
• No new runtime/*.c

claim: PHP runtime migration — dropping Type always-on __compiler_env_local_lookup / __compiler_env_register_putenv (JitEnvLocalKernel owns ABI; peer #32665/#32721).
