Summary
[GLIB] Disable hinting for testing

Currently, when rendering text on the GTK platform, font system options such as antialiasing and hinting are taken into account. While this is generally good, it would be great to have a deterministic testing environment.

There are some tests that differ between GTK and WPE because GTK WebKitTestRunner disables font hinting. It does it by using `GtkSettingsManager` mechanism which doesn't exist on WPE. It would be great to have a way to disable hinting that works on both platforms. It will let us then use the same baselines for such tests.

Or enable hinting for WPE for testing.

Hinting is enabled on WPE by default. And currently, there is no API to change it. If understand it correctly, enabling hinting can lead to flaky or even failing tests.

Ok, that makes sense, then.
