enable mongodb to use cirun

[h-vetinari]

Current mongodb v7 manages to compile about half the objects before running into the 6h timecap (example; around [2385+2/4544] on linux-64, [2398+2/4489] on win-64, etc.) - completely hopeless to get it over the line.

The server can help with Linux builds but we can't do much for Windows, though. I wonder if it's just that mongodb has increased in complexity over time, or whether there's something off in the build.

Also, tagging @conda-forge/mongodb to follow protocol (but I guess we won't hear back, the feedstock has been inactive for a while).

We could conceivably cross-compile from windows from linux. We have linux-64/clang_win-64, but I've never tried to cross-compile across OSes. Perhaps @isuruf or @xhochy have thoughts.

I did a big push late last year to revive it, but didn't get all the way up-to-date due to the timeouts. Now that we have the cirun server, I thought I'd give it another shot.

The only feedstock where we do this is https://github.com/conda-forge/polars-feedstock There is one major constraint though: You cannot have a host environment in that situation. There is a major conda-build bug with prefix replacement. I would rather wait until we have rattler-build in conda-forge than tackling this.

It seems Isuru recently tackled (at least part of) this: conda/conda#13687 🙏
