events: accept boolean options in removeEventListener

[lazerg]

removeEventListener() read capture off the options object only, so the boolean shorthand target.removeEventListener('foo', fn, true) was flattened to capture: false and never matched a listener registered with capture on. addEventListener() already handles the boolean form, so the two went out of sync and the listener stayed attached. Browsers remove it.

Fixes #65244
