Test: platform/mac/fonts/color-bitmap.html

* platform/graphics/mac/FontMac.mm:
(WebCore::showGlyphsWithAdvances): Added. Calls CGContextShowGlyphsWithAdvances()
or CTFontShowGlyphs() depending on whether the font is a color bitmap font.
(WebCore::Font::drawGlyphs): Use showGlyphsWithAdvances(). Don’t include the font’s matrix in
the context’s text matrix when drawing with a color bitmap font, because CTFontShowGlyphs()
factors it in.
* platform/graphics/mac/FontPlatformData.h:
(WebCore::FontPlatformData::FontPlatformData): Added m_isColorBitmapFont member
and initialized it in constructors.
(WebCore::FontPlatformData::isColorBitmapFont): Added this getter.
* platform/graphics/mac/FontPlatformDataMac.mm:
(WebCore::FontPlatformData::FontPlatformData): Initialize m_isColorBitmapFont.
