Brandon Goddard 61d33dd0c3 DevTools: Enhanced accessibility of Network tool Timing tab
This change enhances the accessibility of the Network tool Timing tab
by making the following changes:

 - Add hidden global headers to give column context to screen readers
 - Slight modification of color contrast for section headers (> 4.5)
 - Updated "TIME" to "DURATION" to avoid confusion
 - Applied ARIA heading for soft headers
 - Restructured columns to remove empty table cells from being read
   by a screen reader
 - Added ARIA labels to waterfall column that
   read the start time of the request. (Column 3 indicates the
   duration of that part of the request timing).

Bug: 963183
