immich: use only the prebuilt image-processing libraries

Drop compiling libjxl, jpegli, libheif, libraw, ImageMagick and libvips from
source. The install pulls them from the base image the release's Dockerfile
pins and stops with a clear error when it can't (skopeo/umoci need Proxmox VE
9.1+). The update fetches and unpacks the new image before it stops or changes
anything, so a failure leaves the running install as it is, and installs it
only when the Immich release changes. ~/.immich_base_image records the image;
the old compile leftovers and ~/.immich_library_revisions are removed.
