font downloaded despite no document characters contained within its
unicode-range

Reviewed by Elika Etemad and Brent Fulgham.
Fonts were being downloaded even when no document characters matched their
unicode-range. The root cause was primaryFont() using rangeAt(0) as an
unconditional fallback, which bypasses unicode-range and triggers a download
for the font at that range regardless of whether it's needed.
CSS Fonts 4 §5.2 defines the "first available font" as the first font whose
unicode-range includes U+0020 — whether the font actually contains a space
glyph doesn't matter, only the CSS descriptor.
Apply upstream WPT fix for font-unicode-presented-as-emoji-outline.html
(add U+0020 to unicode-range so the test font acts as first available font).
Rename primary-font-interstitial test to
font-face-unicode-range-failing-source-no-effect
since it tests that a failing @font-face source with non-matching unicode-range
doesn't affect rendering.
