php-in-php: lazy ExceptionBridge from ensureMinimal (#34732)

[PurHur]

Summary

• Closes php-in-php: drop Context ensureMinimalUserStandaloneBodies always-on ExceptionBridge — lazy at TypeErrorRaise call sites (peer #34695) #34732 — drop Context::ensureMinimalUserStandaloneBodies() always-on ExceptionBridge::ensureStandaloneBodies() so thin hello-world AOT no longer NestedJITs TypeErrorRaise / JitThrow during init (peer php-in-php: drop Context ensureMinimalUserStandaloneBodies always-on ObOutputRuntime — lazy at ValueEchoHelper call sites (peer #34642) #34695; Release v1.1.0: fix cold-build-check compile_failed on hello world (LLVM Module.php line 180; re-#24302) #32122 .1 mint class).
• TypeErrorRaise::ensureLinked now implements standalone bodies (with insert-block restore like ErrorRaise); emitClear / emitAbort / emitRaise* ensure before lookup.
• ensureFullStandaloneBodies still eagerly ensures ExceptionBridge for full AOT fixtures.
• php-src: Zend/zend_exceptions.c, Zend/zend_execute_API.c. No new runtime/*.c.

Test plan

• ./script/phpunit.sh --filter 'ContextMinimalStandaloneLazy|ExceptionBridgeRuntimeShrink' → OK (34 tests, 272 assertions)
• ./script/docker-exec.sh -- bash -lc './script/aot-smoke.sh' → 8 passed, 0 failed
• php bin/compile.php -o /tmp/h.bin -r 'echo "hi\n";' && /tmp/h.bin → hi
• AOT typed-param TypeError still catchable (f(int $x); f("a") → caught)
