[Linux] Improve LocationBarViewGtk.

This CL improves LocationBarViewGtk:
1. Add type to search hint.
2. Show/hide selected keyword, keyword hint and type to search hint automatically when resizing the browser window.
3. Use weak gray to display hint text, instead of black.

BUG=11258
TEST=Resize the browser window when one of selected keyword, keyword hint and type to search hint is visible, to see if the hint can be shown or hidden automatically.
