gitlab-ci: Bump CI to Trixie and LTS to bookworm

This includes a few changes, but given that we still want to bisect
things when they break I'm pulling some of the changes into a bigger change.

Here's a list of most noticeable that I had to address in order to make
this switch:

- added a PACKAGES_SPECIFIC env variable to able to pass different
  packages to each version. Some packages basically changed their names
  and need to pass a different name
- added USE_DEBIAN_BACKPORTS and use it when adding -backport apt
  sources for each Debian version
- llvm-19 now requires some additional packages for trixie
- add imghdr for sphinx for trixie
- had to keep use_tls=0 and modified the notes to point now to Trixie
  instead of Bookworm
