Create New Tab page and add an option to set New Tab page as homepage

[haanhvu]

fix #1318

@felipeerias @svillar (and other maintainers) This is a very draft initial implementation. Currently I just added a Homepage option that shows Bookmarks panel like this: https://drive.google.com/file/d/1feSPqru-LJJOmQ3kwPKKuEXal9dirkbr/view?usp=sharing

I'm thinking of creating a specific New Tab page that shows bookmarks (and maybe other things too?). Do you have any ideas on how that New Tab page should look like? Is there any existing layout that I can use for this page?

I think we should be consistent with what others do. See Desktop Firefox, Chrome, or Edge for inspiration

@felipeerias @svillar (and other maintainers) There's bug in the New Tab page that I'm not having any clues to debug. Basically, the hovering point is not exactly as it's showing.

For example:

As you can see, the hovering point is outside of the page item, however, somehow the New Tab page sees the point as being inside the page item, and shows the trash icon.

The reverse is true too: when I actually hover in the item, the page doesn't recognize that and doesn't show the trash icon:

Could you help me to debug this? Thanks!
