[MM-54863] Add permissions manager UI in Edit Server modal, improve permission checks to be less missable

[devinbinnie]

Summary

This PR adds new UI elements to the Edit Server modal, where a user can view/grant/revoke the permissions that are set for each of their servers. Revoking will set the permission to Always Deny, and granting will set it to accept. This should hopefully help users who have missed the prompt, misclicked, or need to change one of the settings. The UI will also include links to System Preferences when we know permissions were denied, or if we can't read the permissions (in the case of notifications).

What I've also done is tried to be a bit more deliberate about some of the permission prompts, so that they will pop as a result of a user's action in most cases:

• The Notifications permission prompt will now pop right after a server is added, and when the app is loaded if the user has not explicitly denied permanently or accepted the prompt. This should hopefully alleviate some missing notification issues where users might hear the ding but won't see a notification.
• The Microphone/Camera prompt is unchanged (since it usually only pops up when you start a call/video call, which is expected), but the app will not double-check macOS system permissions for these when manually enabled on a server.
• Subsequent notifications that appear after the first permission prompt appears will now use the same promiser as the first one, so that if you get a bunch of messages in a row, the messages after the first one will still have notifications appear.

UX Note: This is still using the old modal interface as it will be a lot more work to reskin these modals to use our new modal interface, so I've decided that since this functionality was more important we should try and get it working as quickly as possible, especially for the upcoming ESR. @abhijit-singh please take that into account when reviewing UX, in that we shouldn't be too worried about pixel-perfection since the plan should be to replace all these modals' UI with something newer (need to get rid of Bootstrap :P)

@enzowritescode I've asked for a quick security pass since this changes affect server permissions, has the app open the OS's system preferences, and exposes new functionality to the internal front-end.

I'm not particularly concerned about anything here, but a quick look makes sense to me given what's being touched.

Looks good @devinbinnie, thanks! Also, heads up that the map-marker-outline icon is now in compass and we can use that for the location permission instead of the pin icon.

Done!
