Let WebViewImpl::textInputInfo() query the focused element when selection is empty

This function should return the most accurate information about current text input
based on focus and selection. This change rearranges it so that it can return available
values based on querying the focused element even if the selection is not updated yet.
This will be used in chromium to fix an input method related issue.
