[CSS4] Accept 8 (#RRGGBBAA) and 4 (#RGBA) value hex colors
Move this CSS feature from experimental back to stable under the
prior Blink intent-to-ship [1] (bug 76362) and re-ship (M62).
Block this feature on the Android WebView however (due to chrome
bug 618472) using a AwSettings.java quirk. Also add
setCSSHexAlphaColorEnabled(boolean enabled)
to AwSettings.java which WebViewChromium.java could call once the
TargetSdkVersion to use for this WebView quirk is known.
Add an AwSettingsTest.java test to test that support for this CSS
feature is off by default in the Android WebView.
