Enable Blink Scheduler (but not for WebView or ChromeOS)

Enable Blink Scheduler, but not for WebView or ChromeOS
because there are some tests failing there (see 1 & 2).
Fixing these may take some time and we're keen to gather
performance metrics over the Christmas period.

We'll fix the WebView or ChromeOS problems in the new
year.

ATTN Sheriffs: This patch will expose flakiness in
css3/filters/effect-reference-rename.html there is a patch
in review to fix that:
