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

Problem

Builtin\Type::register() still addFunctions empty always-on shells for __compiler_strtr and __compiler_strtr_array on every JIT/AOT module. StringStrtr already owns these ABIs module-locally via getNamedFunction first + addFunction when absent, but leftover Type empty decls can mint strtr.1 / strtr_array.1 when Runtime ABI drift lands (#31894 / #32122 class).

Peer #32855 removed password crypto shells and left __compiler_strtr* as the next always-on cluster (asserted in TypeDeadPasswordCryptoAbiRuntimeShrinkTest).

php-src reference

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

PHP implementation target

• lib/JIT/Builtin/StringStrtr.php — already declares ABIs module-locally; keep getNamedFunction first
• lib/JIT/Builtin/Type.php — remove always-on __compiler_strtr / __compiler_strtr_array rows; StringStrtr::ensureLinked from Type::initialize
• Keep StrtrTwoStringJitHelper / StrtrArrayJitHelper / user-script strtr() path
• unit shrink test peer TypeDeadPasswordCryptoAbiRuntimeShrinkTest

Done when

• Type.php does not always-declare the two strtr ABIs
• StringStrtr owns the ABIs module-locally; Type::initialize ensureLinks it
• ./script/aot-smoke.sh stays 8/8
• No new runtime/*.c
