Drop object creator builds from CI

[harakka]

Summary

Build "No longer build object creator in CI nor include it in releases"

Purpose of change

Free up CI resources and allow builds to show up on cataclysmdda.org releases page sans object creator.

Fixes #74562

Currently object creator builds fail again and the release workflow doesn't update gh-pages if it doesn't run succesfully.
Building object creator and adding it to releases was done 9 months ago so that people would have a chance to test it out and maybe get someone to develop it again. This has not worked out. The tool only allows fiddling with spells and item groups, both of which need user knowledge to hook them up to rest of the game json, so utility is limited. On the devcord, I haven't seen anyone ever comment on using it. I have seen comments that it has apparently been crashing on start on Windows for a long time but no-one much has noticed.

Describe the solution

Remove object creator from CI. I tried to follow the previous PRs through which added this into CI or changed something about how object creator is built in CI, hopefully I didn't miss anything.

The code is left in repo as dead code as courtesy to KorGgenT https://discord.com/channels/598523535169945603/598535827169083403/1251656064156565565 even though I'd prefer to remove it too, since it has some maintenance burden due to coming up in searches etc. This should really be some kind of sister project IMO by someone who actively works on it.

Describe alternatives you've considered

Testing

Running the release build on my own repo to see the expected release artifacts generate and the experimental release workflow gets the right status. (don't mind the commit msg on that run, had to throw in a few extra commits to get the android builds to finish).

Additional context

@akrieger or anyone else who is clued in on the Windows build side, can you check that this is ok and I'm not missing anything critical. I also saw that some previous cache sizes were chosen based on object creator being built, I don't know if those need to be fiddled with because of this.

Presumably fixes #74562?

I'm fine dropping it, and this seems correct, but FTR what's broken is the appcontainer build, the native windows build is fine (https://github.com/CleverRaven/Cataclysm-DDA/actions/runs/9557490756/job/26344654164#step:15:2636). IDK why we're trying to crossbuild object creator through this indirect vm based mechanism (I guess to exercise that appcontainers do work?) instead of releasing the msvc built version. But as noted, no one active is owning it, it should be laid to rest until someone does.
