cfb686b5 - Migrate `--trim` tests to use JuliaC, delete out-of-date `contrib/juliac` (#62128)

Migrate `--trim` tests to use JuliaC, delete out-of-date `contrib/juliac` (#62128) JuliaC has been the canonical home for these files for some time. It's time we clean up these old copies. As a bonus, this expands our platform / test support for `--trim` to cover all of our CI platforms. Likely requires https://github.com/JuliaLang/julia/pull/62121 for FreeBSD and we'll want to update `julia-buildkite` to remove / filter the unneeded separate `trimming` job. This will need a follow-up PR to https://github.com/JuliaCI/julia-buildkite/ to enable the new `trim` test. --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
