fix abortsignal event names

[Monti-27]

Fixes #5260.

This makes AbortSignal.addEventListener ignore non abort event names instead of throwing.
It keeps the abort listener path the same and adds tests for ignored event names.

Tests:

• cargo test -p boa_runtime abort --lib
• cargo test -p boa_runtime --lib
• cargo clippy -p boa_runtime --all-features --all-targets -- -D warnings

This is also kinda not conformant though. According to the spec, we should be appending all event listeners irrespective of their type to the listeners, just making sure to not push two event listeners with the same type and callback
