cargo.eclass: Add cargo_env helper and use it in compile, test, install
Rust packages have a tendency to rebuild parts during test and install.
It is not clear whether this can be addressed. We were therefore relying
on some environment variables set during the compile phase for
cross-compiling to work in the later phases. This is not ideal,
especially if you need to build for multiple targets.
These environment variables can also be useful in other contexts, such
as the build runner in app-misc/anki.
This change moves the setting of these variables into a separate helper
that is now used in all these phases and can be used by ebuilds too. The
variables are now kept local to each invocation of this helper,
preventing leakage.
