Hob: implement a self-defined notebook visual component for Hob

In recipe selection page, package selection page, and build details page, etc, there is a notebook component which is not gtk.Notebook in the design video.
We implement the visual component with a drawing area, and use it to replace the old notebook in recipe selection page and package selection page. The reasons why we do it are:

1) General speaking, gtk.Notebook doesn't look like the designer worked out. (see https://wiki.yoctoproject.org/wiki/File:Hob1.2-screencast2.mov)
2) And the designer version looks better, for example, there is an indicator to show how many recipes or packages are included, and how many issues happened when building? Very straightforward.
But technically, gtk.Notebook can't implement that, as far as we know.
3) Moreover, there is an entry for "search recipes", and "search packages". How to make it horizontal to the tabs is a problem to us.

Regarding those, we give up gtk.Notebook and use our own.
