Use rustc target metadata for build-manifest target lists This ensures that as long as the target metadata is updated to reflect the current state (tier 3 vs 1/2, host toolchain support), the manifest will also be updated. This avoids an extremely common 'oops' when we move targets between tiers. This mostly removes a bunch of tier 3 targets from manifests. I didn't spot check against produced artifacts but given that they are tier 3 it's probably reasonable to leave it as-is and bug reporters can fix the target metadata in rustc (or we can stop producing artifacts). Follow-up work would ideally lint the artifact list as part of nightly/beta/stable builds as well, but for now this is simple and hopefully removes at common source of extra PRs when modifying targets.
