Bulk-add users to existing org

[rmunn]

Fixes #778.

This adds a "Bulk Add Members" button to the organization page:

Currently the button is only visible to site admins. If we decide to allow org admins to use the Bulk-Add feature as well, it will be quite simple to make it visible to them; adding the correct auth requirements to the GraphQL mutation will be slightly harder but doable.

When you click the button, UI very reminiscent of the bulk-add feature from the project page will show up:

Unlike the project bulk-add feature, the bulk-add feature for orgs does NOT invite users if a username or email address is not found. Instead, it returns a "not found" list to the user and allows them to decide what to do about the not-found accounts:

As per #778 (comment), we're not going to use the checkbox approach, and will instead be creating a bulk-add tool. So rather than fix the merge conflicts in commit 96929b1, I'm going to force-push this PR branch away from 96929b1 and abandon the checkbox idea, thereby making commit 96929b1 likely to be garbage-collected at some point. I don't think there's anything valuable there, though: most of the code is obvious and would be easy to recreate if we need to. I mean, the diff for adding the checkboxes is extremely simple (thanks to Svelte):

I realize I didn't make this clear anywhere, but the bulk add to org feature should be available to org admins. Sorry I didn't clarify that. There's a few things that need to be updated to accommodate that change.

[hahn-kev]

fixed some indenting that got missed in BulkAddOrgMembers.svelte.

Looks good to me.

Merging is currently blocked because "Code scanning has not received results from CodeQL". But the green checkmark is right there in the check results. It's unclear what part of GitHub's system is malfunctioning to not see the CodeQL results, but I'm not going to wait for it. PR has been approved and all checks are green, so I'm checking the "bypass branch protection" box and merging.
