Bug 1731223 - Move wine detection to toolkit/moz.configure. r=firefox…

…-build-system-reviewers,andi

As of now, wine is used with:
- fxc, which is detected in toolkit/moz.configure
- midl, which is detected in toolkit/moz.configure
- ml64 or armasm64, for some assembly sources that aren't used in
  projects that don't include toolkit/moz.configure.

We can thus move it there.
