Allow cancelling test runs when detecting flakes

When using --runs_per_tests_detects_flakes, Bazel runs multiple actions
in parallel and aggregates them such that failed runs are ignored if
there is at least one passing run. This change adds a new flag
--experimental_cancel_concurrent_tests, which causes Bazel to cancel any
concurrent actions when the first passing run is observed. This can
reduce the end-to-end build time in case of large flaky tests.

This is only the first half of the implementation. The code path to
interrupt a running action is currently only used to end the entire
build, and does not post a TestResult for the interrupted action. This
leads to confusing command-line reporting of the results.
