chore(fdk-aac-free): remove component

fdk-aac-free is the "free" Fedora variant of the FDK AAC codec, used by gstreamer, pipewire, freerdp, and (nominally) firefox for AAC audio en/decode. AZL is dropping it from the distro.

The AZL consumers were detached in the preceding commits in this series:

  - fix(freerdp): drop fdk-aac codec dep
  - fix(firefox): drop fdk-aac-free-devel and Fedora fdk-aac patch
  - fix(pipewire): drop AAC bluetooth codec

gstreamer1-plugins-bad-free was removed from the distro in a separate 4.0 commit; no detachment commit is needed here.

gnome-remote-desktop's `BuildRequires: pkgconfig(fdk-aac)` is inside `%if %{with rdp}` and AZL builds with `build.without = ["rdp"]`, so it is already inactive -- no fix needed.

Remove the component definition (base/comps/components.toml), the publish-channel entry (components-publish-channels.toml), the lock file (locks/fdk-aac-free.lock), and the rendered spec (specs/f/fdk-aac-free/). The only leftover references in base/comps/ are explanatory comments in the consumer overlays added by the preceding commits.
