Fixed parts where AbortSignal did not comply with the specification.

• Fixed a memory leak caused by AbortSignal.any holding strong references to dependent AbortSignals
• new AbortSignal() throws an exception
• The onabort property of AbortSignal

Also, modified WPT to execute // META: script= prior to test execution.
