Summary [Chromium] HarfBuzzShaper should take into account combining characters

Some fonts don't have individual glyphs for marks, but have composite glyphs. For example, A font can have a glyph for U+00e9 (e with acute) even if it doesn't have a glyph for U+0301(combining acute accent). We should take into account this fast when we divide a text run into HarfBuzzRuns. If the font also doesn't have composite glyphs, we should try fallback fonts for mark characters.
