rustbuild: Use copies instead of hard links

The original motivation for hard links was to speed up the various stages of
rustbuild, but in the end this is causing problems on Windows (#39504).

This commit tweaks the build system to use copies instead of hard links
unconditionally to ensure that the files accessed by Windows are always
disjoint.

Locally this added .3s to a noop build, so it shouldn't be too much of a
regression hopefully!

Closes #39504
