[text-spacing-trim] Return early if the text is known not to apply

This patch adds a filter for the `text-spacing-trim` to
improve the performance.

The `HanKerning` class currently applies only when the font
has `halt` or `chws`, so the impact to non-CJK fonts is not
visible, but when the font has them, it impacts ~3-5% in the
micro benchmarks.

This patch reduces the impact down by ~1 point.
