Add FC_FONT_HAS_HINT property to see if font has hinting or not.

This may helps to enable autohint only when font doesn't have any hinting

<description>Enable autohinter if font doesn't have any hinting</description>
<!-- Use the Autohinter -->
<match target="font">
<test name="fonthashint"><bool>false</bool></test>
This configuration is available on the major desktop environments.
We shouldn't overwrite it with "assign" unconditionally.
Most clients may picks up the first value only. so using "append"
may simply works to avoid it.
