php-in-php: lazy Stream*/FunctionStatic from ensureFull (#35086)

[PurHur]

Summary

• Drop always-on NestedJIT of StreamLifecycleRuntime / StreamReadRuntime / StreamFilter / JitStreamBucketKernel / FunctionStaticRuntime from Context::ensureFullStandaloneBodies (peer ensureMinimal Stream* php-in-php: drop Context ensureMinimalUserStandaloneBodies always-on StreamLifecycle/StreamRead/StreamBucket — lazy at call sites (peer #34822 / #34439) #34836; ensureFull Assert/Gc php-in-php: lazy Assert/Gc/Progress/Trigger/ReturnPending/LastError from ensureFullStandaloneBodies (Context.php) #35073).
• Call sites already ensureLinked / ensureLinkedForUserScriptLowering before lookup; avoids leftover Context NestedJIT vs Runtime ABI drift (.1 mint class, 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).
• Closes php-in-php: lazy StreamLifecycle/StreamRead/StreamFilter/StreamBucket + FunctionStatic from ensureFullStandaloneBodies (Context.php) #35086.

php-src

• main/streams/streams.c — fclose/feof/fflush/fgetc/fgets lifecycle
• main/streams/userspace.c — stream_bucket_* / brigade
• Zend/zend_compile.c — function-static locals

Test plan

• ./script/aot-smoke.sh → 8 passed, 0 failed
• ./script/phpunit.sh --filter 'ContextFullStandaloneLazyStream|ContextMinimalStandaloneLazyStream|ContextFullStandaloneLazyAssertGc|FunctionStaticRuntimeStandalone|FunctionStaticRuntimeShrink' → OK (15 tests, 116 assertions)
• AOT repro: echo "hi", feof/fclose on php://memory → eof, function-static counter → 12
