top-level: `stdenv.cross` is now only defined with host != build
In practice, this is a strictly stronger condition than target != build
as we never have build = target != host. Really, the attribute should
be removed altogether, but for now we make it work for plain libraries,
which do not care about the target platform. In the few cases where the
compilers use this and actually care about the target platform, I'll
manually change them to use `targetPlatform` instead.

Rewrite a few `stdenv.cross` uses that *should* be `targetPlatform`
The previous commit redefines `stdenv.cross` for the sake of normal
libaries, the most common use-case of that attribute. Some compilers
however relied on the old definition so we have them use
`targetPlatform` instead. This special casing is fine because we
eventually want to remove `stdenv.cross` and use either `hostPlatform`
or `targetPlatform` instead.

cross-stdenv: Only prune most overrides in the final stage
Before all overrides were also pruned in the previous stage, now
only gcc and binutils are, because they alone care about about the
target platform. The rest of the overrides don't, so it's better to
preserve them in order to avoid spurious rebuilds.

Merge pull request #25194 from obsidiansystems/host-target-unconfuse
stdenv.cross is a silly attribute that needs to go leaving the well-defined
hostPlatform and targetPlatform. This PR doesn't remove it, but changes its
definition: before it tracked the target platform which is sometimes more
useful for compilers, and now it tracks the host platform which is more useful
for everything else. Most usages are libraries, falling in the "everything
else" category, so changing the definition makes sense to appease the majority.
The few compiler (gcc in particular) uses that exist I remove to use
targetPlatform --- preserving correctness and becoming more explicit in the
process.
I would also update the documentation aside mentioning stdenv.cross as
deprecated, but the definition given actually erroneously assumes this PR is
already merged!
