Reland "Generate and upload separate coverage data for each target in a build."

Changed the name of the upload directory for per-target metadata so that
it doesn't conflict with where the merged metadata is uploaded.

Previous commit description:

Generate and upload separate coverage data for each target in a build.

This requires us to run llvm-cov on the profdata for each test target.
The code coverage service will aggregate the per-target data to make
reports.

Temporarily skipping this for fuzzers so that the builds don't hit the
20 hr time limit on swarming
