feat: add horizontal nav menu component about fluentui-blazor

[dvoituron]

That would be a very good idea, I think.
Why not improve the existing FluentMenuButton component?
By adding the properties IconStart, IconEnd, Href and updating the (not very fine) "drop down" icon :-)

<FluentStack>
    <FluentMenuButton Text="Dashboard" ButtonAppearance="Appearance.Stealth">
        <FluentMenuItem>Overview</FluentMenuItem>
    </FluentMenuButton>
    <FluentMenuButton Text="Leaderboards" ButtonAppearance="Appearance.Stealth">
        <FluentMenuItem>Maps</FluentMenuItem>
        <FluentMenuItem>Players</FluentMenuItem>
    </FluentMenuButton>
    <FluentMenuButton Text="Play" ButtonAppearance="Appearance.Stealth" />
</FluentStack>

Sounds good. I'll look into that tonight @dvoituron

The navbar that I use is called Header in the layout section of the example and is the FluentHeader tag. Does this help you? Do you put your NavMenuButton in the FluentHeader? Do you use FluentSpacer to separate items?
