feat(ui): resource sorting dropdowns

[alexpaxton]

Closes #16967

Goals

• Working towards better responsive support. Sorting via drop downs works better on smaller screens
• Make the resource lists less noisy and more space efficient
• Ensure the sorting mechanism is always present
• Make it more clear what the current sort is

Changes

• Replace sortable table headers with sort dropdowns in resource lists
  • This ensures the sorting functionality is always present
  • Is more clear that a single sort can be applied at any given time
  • Ensures the filter bar doesn't get squished
• Create a single component for sorting resources
  • The contents of each resource's sorting dropdown are in a single place
  • Hard coded the dropdown items because it was too complex to generate programmatically from the resource type
• Standardize tabbed page headers to use a single component and styles
  • This component is also now responsive
• Moved dashboards empty state into own component

Preview

• http/swagger.yml updated (if modified Go structs or API)
• Documentation updated or issue created (provide link to issue/pr)
• Signed CLA (if not already signed)

This is getting gnarly enough were it might be better as its own component. DashboardEmptyState

This looks almost identical to the DashboardSortDropdown. I'm down to work with you on making one SortDropdown component that can take additional labels to sort by.

Yes! that would be excellent as we'll probs roll this out to other parts of the UI and having a generic component would be great
