fix(events): align addAbortListener ext provider

[andrewtdiz]

Summary

• validate events.addAbortListener() signal/listener arguments through Node-compatible ERR_INVALID_ARG_TYPE paths
• attach abort listeners through the ext events provider NaN-boxed module-helper ABI so abort dispatch fires
• return a disposable object with Symbol.dispose cleanup that removes the registered abort listener

Issue

Part of #2013

Tests

• cargo check -p perry-ext-events
• cargo fmt --all -- --check
• git diff --check
• ./scripts/check_file_size.sh
• npm exec --yes --package=node@26 -- bash -lc './run_parity_tests.sh --suite node-suite --module events --filter add-abort-listener' (3 pass, 0 fail, 0 compile fail)
• npm exec --yes --package=node@26 -- bash -lc './run_parity_tests.sh --suite node-suite --module events --filter event-target' (2 pass, 0 fail, 0 compile fail)

Non-goals

• events.on() / events.once() abort behavior
• broader EventEmitter compile/linkage cleanup
• domain or stream integrations
