Added a single test function script and fix debug-test.sh to be more robust

[mofosyne]

Continuation of #7096 somewhat to address cases where a person may just want to run a single test.

Also discovered that the test binaries expects to be run in the git root context so need to fix debug-test.sh to take that into account.

@josh-ramer you may want to have a quick look a this to see if this would also be useful to you as well.

This is what the output visually looks like. With emphasis on the last three lines for clearer feedback

(Created this to try and more quickly pin down a CI issue)

Actually @josh-ramer when I ran ./scripts/debug-test.sh test 24 with this script I noticed this printout

Ran Test #24: test-eval-callback
GDB args: /home/mofosyne/gitextern/llama.cpp/build-ci-debug/bin/eval-callback "--hf-repo" "ggml-org/models" "--hf-file" "tinyllamas/stories260K.gguf" "--model" "stories260K.gguf" "--prompt" "hello" "--seed" "42" "-ngl" "0"
GDB args @: /home/mofosyne/gitextern/llama.cpp/build-ci-debug/bin/eval-callback~/gitextern/llama.cpp ~/gitextern/llama.cpp/build-ci-debug ~/gitextern/llama.cpp ~/gitextern/llama.cpp

Am i reading it correctly? I would have thought that args[@] would be the same as gdb_args[test_number] but with path expanded, but that doesn't seem to be the case.

[josh-ramer]

That comment is a little deceptive, what the code really does is find paths with /../ in them & replace the path/../path with ../path. There is probably a better solution than that out there if you're pretty skilled in bash scripting. Maybe one easy alternative would be to remove the suffix before /../.

Nice addition, makes sense to be able to execute as well.

[mofosyne]

Maybe you can suggest a better comment? Either way, see if this script is working well for your flow and if I didn't break your gdb flow, then well should be good to go!

I've got a review started, but there are no EC2 spot instance available right now (first time I've had that happen to my workflow) so I haven't run it yet to make sure it works, but as soon as they're available, I plan to run it for you.

[josh-ramer]

LGTM, will run as soon as I have the compute available.

[mofosyne]

@josh-ramer ready

[josh-ramer]

LGTM

[mofosyne]

@josh-ramer see if you can press approve as there needs to be one other approval before it can merge in.

[josh-ramer]

LGTM

Looks like I don't have write access. I think that means I'd have to be added as a collaborator like you.

@josh-ramer thanks. It's in now, hope it helps!
