cmd/coordinator: handle new dist test names with current adjust policies

The coordinator has some custom logic for "go_test:*" dist test names
involved in partitioning, merging, and sorting them using historical
test timing data. We also have many builder-specific dist test adjust
policies, and some parts of them have become out of date (e.g.,
macTestPolicy skips "wiki", a dist test that's long gone).

Go 1.21 is simplifying the naming pattern for dist test names, and
we want to do that without having to manually update the (many!)
existing adjust policies, as well as to avoid breaking or creating
a need to re-engineer the existing mechanisms that make "go_test:*"
dist test names special.

Make that possible by remapping the 'go tool dist test -list' output
from the new "pkg[:variant]" format to the previous format (or pass it
through unmodified if it's already in the old format) for the purpose
of dist test adjust policies only. Also keep the raw unmodified dist
test name around since it's needed for invoking said dist tests.

For golang/go#37486.
For golang/go#59990.
