(core) Implement much of the general AccessRules UI.

Summary:
- Factored out ACLRuleCollection into its own file, and use for building UI.
- Moved AccessRules out of UserManager to a page linked from left panel.
- Changed default RulePart to be the last part of a rule for simpler code.
- Implemented much of the UI for adding/deleting rules.
  - For now, editing the ACLFormula and Permissions is done using text inputs.
- Implemented saving rules by syncing a bundle of them.
- Fixed DocData to clean up action bundle in case of an early error.

Test Plan: WIP planning to add some new browser tests for the UI
