NavigationBar2 control

[promag]

This is an alternative to the existing NavigationBar component. The layout is such that the center section is horizontally centered when possible, and the right section is right aligned. Also, Loaders are avoided with this new approach.

Since the approach is quite different from the other navigation bar, a full refactor would be substantial, harder to test and subject to breaking changes. For that reason, both implementations will be available for a short period of time. More pull requests will follow to replace the old implementation once this is accepted.

Finally, the new navigation bar is used on the Peers, NodeRunner, and ThemeSettings pages.

tested ACK, desktop ver built on Ubuntu 22.04.

I've build #343 on top of this and used NavBar2 for the popup and the title was centered more accurately.

Concept ACK

In that case, number the PR's and add a title for the series: (1/n) Reimplement NavigationBar Control

nice, we should do this more often. Having helper components.

+1 for navbar2, this can be defined when defining the page, instead of defining the navbar components where the Peers page is to be used.

Not sure what is the suggestion.

[jarolrod]

There is no suggestion, just a comment on what I like about this :)

This is an improvement over using loaders in the original NavigationBar, and sets a foundation for where the navbar needs to go. Last place that still uses the original navbar is InformationPage, but this requires more reworking and the work needed can change depending on when we move to a UI flow of stack views.
