Stop building and shipping openspecfun

[ararslan]

At this point, this should be a non-functional change, since openspecfun isn't being used internally anymore as of #22603. It is technically breaking, however, since any code that was referencing Base.Math.openspecfun or explicitly ccalling into openspecfun will be broken.

I'm marking this as WIP until I have binary downloading/building finished in SpecialFunctions. (It's close.) Once that's done I'll remove the "WIP." Ready. 😎

Fixes #22390.

@jlbuild !nuke

Pkg.clone("https://github.com/JuliaMath/SpecialFunctions.jl.git")
Pkg.checkout("SpecialFunctions", "master")
Pkg.build("SpecialFunctions")
Pkg.test("SpecialFunctions")

Okay, I'm not sure whether jlbuild is still up and running, but either way this works on CI using the binaries I built for it as well as locally on a system without binaries, so I guess the jlbuild run should be mostly unnecessary anyway.

So this is good to go!

Hmmm, so something is borked in jlbuild, I'm getting backtraces from HttpServer.jl:

In any case, I'm going to kick the server over and see if that fixes anything.

[ararslan]

If you've kicked the server, should I try invoking jlbuild again?

[staticfloat]

It looks like there are unrelated testing errors with the buildbots. :/

Unrelated here, but we had at some point discussed translating the openspecfun code to Julia using @nolta 's script. That might be worth visiting once this is split off and stabilized(but obviously some non-trivial work).
