ci: Disable llvm/debug assertions on x86_64-mingw

[alexcrichton]

Tracked at #59637 for re-enabling this commit disables assertions to
hopefully bring the runtime for this builder under control.

Looking at a random build x86_64-msvc also takes more than 3 hours, and while it's average is lower it's still high. Do we also want to disable some assertions there?

[alexcrichton]

Sure yeah, I've gone ahead and done it for the three currently slowest builders
