Fix flaky Web Extension exception tests on debug

https://bugs.webkit.org/show_bug.cgi?id=270997
rdar://124632659

Reviewed by Timothy Hatcher.

It appears that these error tests were timing out on the bots. This PR fixes them in two ways:
1) Upping the timeout on debug builds to 6 seconds (since debug builds are slower to run these tests)
2) Splitting the tests that are timing out into separate tests
