[Mac] Draw the results label correctly in the findbar.

Adds common base classes (StyledTextField and StyledTextFieldCell) for both the find bar and omnibox text fields.

BUG=http://crbug.com/19550
TEST=Findbar results label should not be overdrawn by find text.
TEST=Autocomplete drawing (keyword, hint, lock icon) should not be affected.
