Clean up WPT TestExpectations for CSS animations and transitions

external/wpt/css/css-animations/Element-getAnimations.tentative.html
external/wpt/css/css-transitions/AnimationEffect-getComputedTiming.tentative.html
(turned on and baselined, code appears to have been fixed earlier)

external/wpt/css/css-transitions/CSSTransition-startTime.tentative.html
(now has same behavior reargless of when in frame the test is started)

external/wpt/css/css-transitions/properties-value-*
(fix duration to allow for CPU stress and add RAF before checking event
handlers are called, using guideline in
https://web-platform-tests.org/writing-tests/testharness-api.html#timeouts-in-tests
"Note that timeouts generally need to be a few seconds long
in order to produce stable results in all test environments.")

external/wpt/css/css-transitions/no-transition-from-ua-to-blocking-stylesheet.html
(marked flaky instead of always-fail, test sometimes passes)

REMOVE external/wpt/css/css-transitions/transitions-animatable-properties-01.html
(old and flaky duplicate of properties-value-001.html)
(serial timeouts add to close to 60s, causing harness timeout in CI)
