[omnibox chrome:omnibox]: Add full table header names to their tooltips.

Currently, only headers for boolean fields have their name included in
their tooltip. On small browser windows, the displayed header names can
become truncated. To avoid confusion when interpreting "Ass..." or
"Provider & ...", this CL adds the full header names to their tooltips,
followed by a new line.

Additionally, this CL expands the tooltip for the header "URL &
URLStripped" to describe both fields; previously, it only described URL.
