Use all projects parameter to resolve image fingerprints in permission config

[edlerd]

Done

• Use all projects parameter to resolve image fingerprints in permission config
• Show project for images in permission selector
• Since Add all projects support to fetch images lxd#14126 got merged, this is now unblocked. For older versions (non latest/edge) the parameter won't harm so we don't need to consume the api extension for this feature.

QA

1. Run the LXD-UI:
   • On the demo server via the link posted by @webteam-app below. This is only available for PRs created by collaborators of the repo. Ask @mas-who or @edlerd for access.
   • With a local copy of this branch, build and run as described in the docs.
2. Perform the following QA steps:
   • configure image permissions for a lxd deployment that has images in different projects
   • the images from all projects should be resolved to names in the permission selection and editing when assigning permissions to groups.
