Previously, each url was checked with `(Authorizer).CheckPermission`. With the fine-grained authorization driver this may use more database calls than is necessary. This commit refactors the permission check to use a permission checker instead, if there are multiple entities of a given type. (See similar logic in `lxd/project.FilterUsedBy`).

Can we standardise this pattern into a helper function we can call in each appropriate place?

This is similar to project.FilterUsedBy except that this one returns an error if any are unauthorized - rather than filtering them out.
I suppose here I could write a method FilterByEntitlement, then FilterUsedBy would call it with can_view and this function would call it and check if the length of the input list is equal to the length of the output list. I think that might be less clear though. Not sure 🤔
