rules_rust: enable pipelined compilation. (#1275)

Pipelined compilation allows better parallelism during builds as it
allows libraries to generate lightweight metadata files to unlock other
depencies. These metadata files (.rmeta) can only be used to unlock
library -> library dependencies and do not affect builds in any other
way. This is currently the default in cargo:
https://internals.rust-lang.org/t/evaluating-pipelined-rustc-compilation/10199.

Pipelined compilation will be disabled by default and will need to be
enabled via flag. Pipelined compilation is not supported on windows and will
thus always be disabled.
