feat(@clayui/navigation-bar): Adds fluidSize prop to customize container-fluid width

[pat270]

https://liferay.atlassian.net/browse/LPS-192418

@matuzalemsteles I added the prop fluidSize to ClayNavigationBar. We currently allow ClayLayout.ContainerFluid to omit outputting the class container-fluid-max-{size} if the size=false. Should we add a new fluidSize, something like fluid or fluid-layout, in ClayLayout.Container to do that instead?

I'm not sure, ClayLayout.ContainerFluid is just a wrapper on top of ClayLayout.Container with a simple abstraction so I don't think it would be necessary.
