Using the same CARGO_TARGET_DIR for all builds prevents us from
building for platforms in parallel, since cargo will lock the
directory to only run one build at a time.
Use the same directory for clippy as well, and ensure that
clippy won't invalidate caches created by run_tests.
This reduces the build time for tools/presubmit by about 50%.
Another advantage is that rust_analyzer and run_tests will no longer
block each other or invalidate the cache when run with different
feature flags.
Note: This introduces two subtle changes to the build that required nit
fixes:
- build.rs files are now run through clippy as well
- common/* crates are now also built for the target architecture instead
the host.
