Reland after reason for printing test timeouts has been identified in
issue 996185.

This will prefer performing DWrite API based font fallback on all
Windowses, particularly on Windows 8.0 and below, where API based
fallback was previously not available and hard-coded lookup tables were
used. A content feature is used to flip the switch on this as a
last-resort deactivation method, should this lead to unexpected fallback
problems.

Sheriffs, if there are individual layout tests failing with differences
in arrow icons or different fonts used for Chinese, Japanese or Korean
text, please disable the test and assign it to me - I will add the new
baselines.
