Supports FontList in Textfield.

The current interface of Textfield does not support FontList while RenderText supports FontList.  This CL supports FontList in Textfield.

The direct cause of crbug.com/263169 was that RenderText always uses the IDS_UI_FONT_FAMILY_CROS font set ignoring what font is specified for Textfield on ChromeOS.  (See https://code.google.com/p/chromium/codesearch#chromium/src/ui/views/controls/textfield/native_textfield_views.cc&q=IDS_UI_FONT_FAMILY_CROS&sq=package:chromium&type=cs&l=88 )

The Omnibox font size is carefully calculated, but the font is ignored right now.

This CL changes the following:
- Supports FontList in Textfield so Omnibox layer can specify the font set, such as IDS_UI_FONT_FAMILY_CROS, for the underlying Textfield.
- Makes NativeTextfieldViews follow the specified font set via Textfield on ChromeOS.

BUG=263169,263196
TEST=Test manually.
