leanback: allow customize title view branding
Added theme attribute browseTitleViewLayout to customize layout
for title view. The theme attribute is shared across all
BrandedFragment subclasses including BrowseFragment, DetailsFragment,
VerticalGridFragment and ErrorFragment.
Custom layout can provide a customized widget which implements
TitleViewAdapter.
Expose hidden base BrandedFragment class to public in API, this fix
issues of API generator does not handle public methods in
hidden base class.
Refactored ErrorFragment to use BrandedFragment.
