Ryan Currah 6a4bc8d17e cmd/go: cache coverage profile with tests
This CL stores coverage profile data in the GOCACHE under the
'coverprofile' subkey alongside tests. This makes tests which use
coverage profiles cacheable. The values of the -coverprofile and
-outputdir flags are not included in the cache key to allow cached
profile data to be written to any output file.

Note: This is a rebase and squash from the original PRs below that
was created/closed/abandoned by @jproberts and @macnibblet that I
plan to maintain.

- https://github.com/golang/go/pull/50483
- https://github.com/golang/go/pull/65657

I made improvements to the change based on feedback from @bcmills in Gerrit
https://go-review.googlesource.com/c/go/+/563138.

From @macnibblet:

I don't know if anyone has considered the environmental impact
(Yes, of course, dev experience too), but on a team with 3 backend
developers, when I replaced our CI Golang version with this build,
it reduced the build time by 50%, which would have
equated to about 5000 hours of CI reduced in the past year.

Fixes #23565
