Revert of remove unused (by clients) SkUnitMapper (https://codereview.chromium.org/283273002/)
Reason for revert:
does not address all legacy callsites in chrome.
e.g.
[13:45:32.091872] ../../ui/native_theme/native_theme_base.cc:608:76: error: no matching function for call to ‘SkGradientShader::CreateLinear(SkPoint [3], SkColor [3], NULL, int, SkShader::TileMode, NULL)’
[13:45:32.091919] gradient_bounds, colors, NULL, 3, SkShader::kClamp_TileMode, NULL));
