Shorten duration of audio in audiobuffersource-loop-points WebAudio test

This test generates 7+ sec of audio, which takes a long time on debug
builds.  Reduce the length to 1.8 sec by making the notes much shorter and only
generating 60 notes (5 octaves) instead of 72. This shouldn't affect
the quality of the test.

Running local tests for linux, mac, win, and android shows that all of the platform tests are identical and can be removed in favor of just the one reference.

The "children transform layer" needs an anchor point

This layer houses what used to be the sublayer transform. It needs to be applied
about the layer's anchor point, so we must set it.

Make any sort of ligatures, not just common ligatures, use the complex text path.

We can remove the incorrect hack in the layout test that used
common-ligatures, which forces the complex path.

Bing Maps API fails to display properly

When forcing a style update, we failed to actually force the update because of
an early-out in updateStyle. This CL teaches that early-out to respect the
Force option, fixing a regression in displaying the Bing Maps API.
