[omnibox chrome:omnibox]: Use header tooltip when searching boolean properties.

Before, we used the column header text when searching by boolean properties.
When we replaced the headers with 1 letter abbreviations, this broke searching
boolean properties. I.e., to search for results that could be the default match,
you'd have to type 'is:d', but 'is:default' would no longer work. This CL
changes searching to use the first line of the tooltip text instead of the
header text.

The current tooltip names are:
  - Can be Default
  - Starred
  - Has Tab Match
  - deletable
  - From Previous
  - Done
