ui: Redesigns for the token/policy/roles listings pages

[johncowen]

This PR follows on from #8137.

The new designs for composite-rows that we used for the new token listing page need to be rolled out across all of our listings. A lot of our listings have an 'actions' menu on the right hand side, and in order to add these 'actions' we use several components that work together to make the actions menu plus confirmation etc.

As we reuse various components working together to make this menu, it means it is quite verbose to set up and add to the templates.

Therefore this PR begins by creating a better way to add these menus using a mix of BlockSlots and Contextual components to make the menus less complicated to add.

Menu items and their potential confirmations are now simpler <Action>ActionName</Action> and <Confirmation> Contextual components. All of the wiring together of the various components is now carried out in one place in <ListCollection /> and therefore hidden away from where we need to repeat these menus over and over again.

Admittedly the wiring together of these components index <ListCollection /> is slightly complex due to the contextual components and passing information/actions around. But the thinking is that once all of our listings are using this new approach we can simplify this at a later date.

Secondly this PR then uses these new additions to implement new <ConsulRoleList /> and <ConsulPolicyList /> components.

The pageobjects for the above are also a mixture of various composable component pageobjects, and we stop using our deleteable pageobject helper here in favour of using a pageobject file from the <MorePopoverMenu /> component. Eventually we should be able to phase out these deleteable etc helpers for component pageobjects instead.
