Consolidate Index Management missing privileges UX

[cjcenizal]

We need to consolidate the way missing privileges are handled by the Index Management UI. The Indices, Data Streams, and Index Templates UIs all handle these errors similarly, but Component Templates does things differently.

When testing with a user with the following privileges, Index Management is accessible, but the Indices and Data Streams tabs report the privileges error.

index_management_user: {
  elasticsearch: {
    cluster: ['monitor', 'manage_index_templates'],
  },
},

Reducing it further shows error for index and component templates too:

index_management_user: {
  elasticsearch: {
    cluster: ['monitor'],
  },
},

Note: Component templates has a specific privileges check for manage_index_templates and renders a custom error message.
