Test that purging inactive font data clears the shaped text cache

Reviewed by Tim Nguyen.
308842@main made GlyphBuffer hold weak Font references, so a GlyphBuffer cached
in a FontCascadeFonts shaped text cache can outlive its Fonts once they are
purged. 315309@main fixed this by clearing those caches in
FontCache::purgeInactiveFontData. Add a regression test that populates the
shaped text cache, purges inactive font data, and verifies the cache is
emptied. Expose TextMeasurementCache::isEmpty so the test can observe the cache.
